1. Preheat the broiler. Line a baking sheet with aluminum foil.
2. Scoop the insides out of the roll, place the roll on the baking sheet, and lightly toast under the broiler for 1-2 minutes. Place the roll on a plate and set aside.
3. In a pan coated with nonstick spray, sauté the chicken until it is no longer pink inside, 3 to 4 minutes per side.
4. Transfer the chicken to the baking sheet, top with marinara sauce, mozzarella cheese and Parmesan cheese. Place under the broiler until the cheese is melted and bubbling. Using a spatula, remove the chicken Parm from the oven and place on a toasted roll.
