XOCHIPILLI'S CHICKEN UNDER A BRICK

Steps:

• Open chicken and place on a work surface, skin side up. Using your palms, firmly press on breastbone to flatten the breast. Season chicken all over with 1 tablespoons salt, 1/2 teaspoons black pepper, and cayenne. Place in a baking dish; rub with 1 tablespoons oil, sprinkle with lemon zest, and scatter rosemary over. Let stand at room temperature for 1 hour.
• Build a medium-low fire in a charcoal grill, or heat a gas grill to medium. Place chicken, skin side down, on grill and place a foil wrapped brick or heavy skillet on top of chicken to weigh it down. (This will expose more skin to direct heat, making it crispy; the chicken will also cook faster.) Cook until skin is crispy and golden brown, about 15 minutes.
• Using tongs, set brick aside. Turn chicken, cover grill, and cook for 10 more minutes. Continue cooking and turning chicken every 10 minutes, covering grill between turns, until an instant-read thermometer inserted into the thickest part of the thigh registers 165 degrees F, about 50 minutes total. Transfer to a carving board; let chicken rest for 10-20 minutes. (Resting will make for juicier meat.) Transfer to a carving board; let chicken rest for 10 minutes before carving.
• While chicken rests, add more coals to fire if necessary to increase heat to medium, or heat gas grill to medium-high. Season chile, bell pepper, and onion with salt and pepper. Grill (or use a grill basket) over medium heat, turning occasionally, until softened and charred in spots, about 12 minutes. Transfer onion to a medium bowl. Transfer chiles and peppers to a work surface and cut lengthwise into 1-inch slices. Add to bowl with onion. Add 1/4 cup vinegar to vegetables and toss to coat.
• Heat 2 tablespoons oil in a small skillet over medium-low heat. Add garlic and cook until soft but not browned, about 4 minutes. Add basil and stir to wilt. Add basil mixture to bowl with onion. Season vegetables to taste with salt and more vinegar, if desired.
• Rub cut side of avocados with remaining 1 tablespoons oil, season with salt, and sprinkle with chili powder. Grill, cut side down, until avocado is gently warmed and flesh is golden brown, about 3 minutes. Serve chicken with vegetables and avocados.
