Steps:

• Preheat the oven to 450 degrees F (230 degrees C). Lightly spritz bottom and sides of a medium baking pan with olive oil spray.
• Using a sharp knife, carefully slice into the side of each chicken breast to form a pocket but do not slice all the way through. Season the insides and outsides with salt and pepper.
• In a small bowl, combine diced avocado and the bacon. Divide the mixture in half and stuff each chicken breast. Use toothpicks to secure the pockets and place into baking pan.
• Mix together panko, mozzarella cheese, and olive oil in a small bowl. Brush 1 tablespoon pesto on top of each breast. Cover each breast with the panko mixture, pressing into the pesto so mixture adheres.
• Roast in the preheated oven until chicken is no longer pink in the center and the juices run clear, 20 to 25 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).

ROASTED CHICKEN WITH FRESH GARLIC AND SPINACH STUFFED UNDER THE SKIN AND WILD MUSHROOM MASHED POTATOES

Steps:

• Mix thoroughly and reserve for seasoning the chicken.
• Preheat oven to 340 degrees. Brown off the garlic lightly in olive oil and place to the side. Then saute your spinach quickly until starts to wilt. Remove from the flame and add to lightly browned garlic. Chill. Slide your fingers in between the skin and the breast meat of the chicken. Neatly slide your spinach and garlic mixture in between the skin and the breast meat. Truss your chicken and lightly sprinkle some of your herb mixture over the top of chicken and rub with olive oil. Bake in a pre-heated 340 degree oven for about 45 minutes.
• While the potatoes are still warm add your heated milk, butter, mushrooms, and demi-glace. Mix thoroughly until incorporated.

CHICKEN STUFFED WITH SMOKED MOZZARELLA, ROASTED TOMATOES AND BROCCOLI RABE OVER POTATOES WITH MARSALA SAUCE

Steps:

• To roast vegetables, preheat oven to 400 degrees F. Place tomatoes and rapini on a baking sheet and season with salt and pepper and coat with 1/4 cup of the olive oil. Roast the vegetables until tender, then remove and allow to cool.
• Begin the Marsala sauce by heating 1/4 cup of the oil in a saute pan and cooking the shallots or onion gently until translucent. Deglaze the pan with the wine and add the stock and fresh thyme. Allow to reduce by 2/3.
• For the stuffed chicken, preheat oven to 350 degrees F. Lay a long piece of plastic wrap over your cutting board and tuck it underneath the sides of the board. The chicken breasts should be placed on the covered cutting board, skin side down, with enough space between them so they can lay flat after you "butterfly" them. To make the butterfly cut, carefully slice open (without slicing the chicken all the way through) and spread the flesh of the chicken out so you will be able to pound it out into a single thin piece on which you will place stuffing and then roll up. Season the breasts with salt and pepper. Then put another length of plastic wrap over the seasoned chicken breasts and flatten with meat mallet to integrate the seasoning into the chicken. (Covering the chicken with the plastic will also keep the mess down when you pound with the meat mallet.) Pound chicken thin and remove plastic. Lay sliced smoked mozzarella on each breast followed by broccoli rabe and roasted tomatoes. Fold in each end and roll tightly, securing with toothpicks as needed, and placing on a baking sheet. Season with salt and pepper and brush with 2 tablespoons olive oil. Place in the oven and roast until fork tender about 45 to 50 minutes.
• Place the potatoes on a baking sheet, season with salt and pepper, and coat with olive oil. Place in the oven and roast potatoes until they are also fork tender.
• Strain Marsala sauce and whisk in butter to finish. Season with salt and pepper, as needed.
• Remove any toothpicks securing the chicken. Slice each chicken roll to reveal the stuffed interior. Place on serving plate with roasted potatoes. Spoon Marsala sauce around chicken. Garnish with chopped chives.

• Spread 1/4 of cream cheese mixture on skinless side of each chicken breast half; top with 1 piece of bacon. Roll up chicken, jellyroll fashion, lifting skin and tucking roll under skin.
• Whisk together egg and milk in a bowl. Combine baking mix, Creole seasoning, and pepper in a shallow dish. Dip chicken rolls in egg mixture; dredge in baking mix mixture.
• Pour oil to depth of 2 inches in a large skillet; heat to 350 degrees F. Fry chicken rolls, in batches, 10 to 12 minutes or until dark brown and done, turning chicken rolls often. Drain on a wire rack over paper towels.
• Spoon 1/4 cup Roasted Red Pepper-and-Vidalia Onion Gravy on each of 4 individual serving plates; top with 1 chicken roll. Drizzle with remaining gravy.
• Dice 1 onion half; set aside.
• Cut remaining onion half into slices. Place onion slices and bell pepper, cut sides down, on a baking sheet lined with non-stick aluminum foil; drizzle with oil, and sprinkle with salt.
• Broil onion slices and bell pepper halves 5 inches from heat about 10 minutes or until bell pepper looks blistered. Place bell pepper halves in a zip-top freezer bag; seal and let stand 10 minutes to loosen skin. Peel bell pepper halves, and dice 1 half. Reserve diced bell pepper and remaining half. Dice roasted onion, and set aside.
• Melt butter in a large skillet over medium-high heat. Add reserved diced raw onion, and saute 10 minutes or until onion begins to brown. Stir in flour; cook, stirring constantly, 5 minutes, or until flour mixture is caramel-colored. Stir in chicken broth and Creole seasoning. Reduce heat to medium, and cook, stirring constantly, until thickened.
• Process gravy mixture and reserved bell pepper half in a blender until smooth, stopping to scrape down sides.

STUFFED CHICKEN BREAST IN CURRY SAUCE OVER ROASTED POTATOES AND CAULIFLOWER

Steps:

• Potatoes and cauliflower:
• Preheat the oven to 350 degrees F.
• On a large baking sheet toss together the cauliflower, potatoes, chervil, raisins, olive oil and salt and pepper, to taste. Arrange in a single layer on the baking sheet and roast until the potatoes are tender, about 25 minutes. Remove the potatoes to a bowl and set aside.
• Chicken: In a blender or food processor, combine the grapes, walnuts and dates and blend until smooth.
• Put the chicken breasts between 2 sheets of plastic wrap and, using a meat mallet, pound the chicken until evenly flat and thin. Remove the top sheet of plastic. Season the chicken with salt and pepper, to taste. Divide the grape mixture between the chicken breasts, topping each piece with about 2 tablespoons of the filling. Using the plastic as your guide, roll up the chicken around the filling.
• Put the flour, eggs and bread crumbs in separate dishes. Season the bread crumbs with the garlic powder, onion powder and salt. Dip the chicken rolls into the flour, coating completely, then into the egg and finally into the bread crumbs. Chicken should be coated completely with each step of the breading process.
• Heat 2 tablespoons of oil in a large oven-proof skillet over medium-high heat. Pan fry the chicken until golden brown on all sides, turning after a few minutes on each side. Transfer the pan to the oven and bake until cooked through, about 15 minutes.
• Curry sauce: Melt the butter in a skillet over medium heat, then add the onion and curry powder. Cook for 2 minutes then whisk in the flour and cook for 1 minute. Whisk in the chicken stock and bring to a simmer. Whisk until the sauce is thickened and smooth.
• Remove the chicken from the oven to a cutting board and slice. Spoon a bed of potatoes and cauliflower on each serving plate and top with curry sauce.

CHICKEN BREASTS STUFFED WITH ZUCCHINI, ROASTED RED PEPPER, AND GOAT CHEESE

Steps:

• In a skillet cook the onion in 1 tablespoon of the oil over moderately low heat until it is softened, add the zucchini, and cook the mixture, stirring, for 1 minute, or until the zucchini is tender. Stir in the red pepper, the goat cheese, and salt and pepper to taste and cook the mixture, stirring, until cheese is melted. Transfer the mixture to a small bowl and let it cool slightly.
• With your fingers make a pocket for the filling in each chicken breast half by separating in skin from the meat, being careful not to tear the skin and keeping the skin attached along most of the edge. Stuff each pocket with half the filling with a small spoon, packing it and pulling the skin to cover the filling completely, and secure the pockets with wooden picks if desired. In a large skillet heat the remaining 1 tablespoon oil over moderately high heat until it is hot but not smoking and in it sauté the chicken, beginning with the skin side up, for 2 minutes on each side. Reduce the heat to moderate, cook the chicken for 9 minutes on each side, or until it is cooked through, and divide it between 2 plates. Pour off the fat from the skillet, to the skillet add the broth, and boil the broth, scraping up the brown bits, for 30 seconds. Strain the sauce and pour it around the chicken.

SAUSAGE-STUFFED ROASTED CHICKEN BREAST AND SIDE DISHES

Steps:

• Pre-heat the oven to 350 degrees
• To prepare chicken: If frozen, thaw the chicken breasts, rinse, pat dry and set aside. Using a large flat plate prepare the "dredging flour" with salt and pepper and set aside. Take 2 of the maple sausage links and cut them into half so you have 4 pieces. Open the chicken breasts and remove the "fillet" and reserve for another use. Make a small pocket in the inside of the breast. Place 1 of the sausage pieces in the pocket and wrap the breast around it creating a closed container surrounding the sausage. Dredge the breasts in the prepared flour and set the 4 breasts on a clean plate. Heat 2 tablespoons of olive oil in an oven safe lidded skillet. Starting with the open end first, brown the breasts fully being careful not to open the closed breast. As the breasts cook, the opening will seal making it easier to finish the searing and browning. Once fully browned cover and place in the oven and cook through. Using a small saucepan, combine basil pesto and cream and mix well. Over medium heat reduce the pesto/cream mixture by 1/3 and set aside.
• For the spinach: Plump the raisins in a cup of warm water and set aside. Cut the remaining sausage in to small pieces and set aside. Remove the frozen spinach from the package. Carefully cut the blocks into 8 large pieces. Using a lidded skillet, saute the onion in 2 tablespoons of olive oil for 2 minutes. Add the sausage and lightly brown. Add the frozen spinach and cover. When the spinach has totally thawed combine the onion and sausage and season with salt to taste. Add the raisins and their liquid and finish cooking, about 10 minutes. Allow the liquid to evaporate but do not dry out completely.
• Tomatoes, zucchini flowers and string beans: Using a non-stick pan quickly sear the tomatoes in some butter. Do not cook them longer than 30 seconds on each side. Reserve the pan and juices for cooking the zucchini flowers. Gently open the zucchini flower and remove the piston from its center. Replace it with a small piece of brie and close the flower. Using the same pan from above quickly cook the zucchini flowers. They are done when you see the Brie melting. Remove from the pan and place 1 on each of the seared tomato slices. Set aside. Bring a pot of lightly salted water to a boil. Add the string beans and cook until your desired doneness. Dress with extra virgin olive oil and some freshly squeezed lemon. Season with the freshly ground black pepper.
• Remove the roasted chicken breasts from the oven and remove the skin. Place one breast centered on the lower third of the individual plate. Place a zucchini flower topped tomato on each plate centered above the breast. Frame the plate with some dressed sting beans on one side and the sauteed spinach on the other. Slowly re-heat the basil pesto sauce and place 2 to 3 spoonfuls of the sauce on each breast. Serve warm and enjoy.
