Preheat oven to 400°. Split Turano Bambino Rolls. Place open rolls on baking sheet. Melt butter and stir in garlic powder. Brush butter on cut side of bread. Bake bread for 8-10 minutes until lightly toasted. Meanwhile, warm olive oil in a large skillet over medium-high heat. Sprinkle chicken with ½ of salt and ½ of pepper. Cook until browned, flip over and continue until cooked through about 8 minutes total. Remove bread from oven. Sprinkle Parmesan cheese over both halves of rolls. Stack cooked chicken, marinara sauce, and mozzarella cheese on the roll. Bake 5 minutes or until cheese is bubbly and melted. Close rolls and serve!
