KINGS FLAT IRON STEAK SANDWICH

Steps:

• Preheat an oven broiler on high heat.
• Open the sandwich rolls and spread each with about 1 teaspoon of softened butter. Sprinkle each buttered sandwich roll with about 1/2 teaspoon garlic powder.
• Broil the sandwich rolls about 5 minutes, until the edges are slightly charred. Set aside.
• Heat a large, heavy skillet over high heat, and add the vegetable oil. When oil just begins to smoke, drop in the flat iron steaks and quickly sear until steaks are browned, about 3 minutes. Flip the steaks and sear the other side for another 3 minutes; remove steaks immediately, or lower the burner temperature and cook to the desired degree of doneness. Set steaks aside and keep warm.
• Assemble each sandwich roll with spinach leaves, tomato and avocado slices on one side, and 2 slices of mozzarella cheese on the other side. Sprinkle the tomato and avocado side with about 1/2 teaspoon of balsamic vinegar, and place a hot browned steak on the mozzarella cheese. Fold each sandwich closed to serve.
