Chicken Fajita Bubble-Up Bake

Heat oven to 375 °F. Lightly spray 13x9-inch (3-quart) glass baking dish with cooking spray. Separate dough into 8 biscuits. Cut each biscuit into quarters; place in medium bowl. Sprinkle with 1 tablespoon of the fajita seasoning mix; toss to coat. Set aside. Heat 10-inch skillet over medium heat. Add bell peppers and onion; cook 3 to 5 minutes, stirring occasionally, until peppers and onion blister and char slightly or until cooked to your liking. Remove peppers and onion from skillet; keep warm. Return same skillet to medium heat. Add oil and chicken; cook on each side until browned and no longer pink in center. Sprinkle remaining fajita seasoning mix over chicken. Add water; cook and stir until sauce thickens. Return peppers and onion to skillet; stir to coat. Spoon chicken, peppers and onion into baking dish. Top with seasoning-coated biscuit pieces. Bake 20 minutes or until biscuit pieces are thoroughly baked and light golden brown. Sprinkle cheese over top; bake 5 minutes longer or until cheese is melted.
