Place the chicken breasts flat on the bottom of a baking dish.
Cover with the marinara sauce, using more or less to taste.
Put the cheese slices over the sauce.
Mix the bread crumbs and parmesan cheese and then spread the mixture evenly over the top of the dish.
Bake at 350F for 35-45 minutes or until chicken is cooked all the way through.
Serve hot over pasta.
