In a shallow bowl, combine egg white and milk. In another shallow bowl, combine the bread crumbs, Parmesan cheese and seasonings. Dip each chicken breast in the egg white mixture, then in the crumb mixture.
In a large skillet; cook chicken on both sides in butter until chicken is golden brown and crispy and juices run clear. Sprinkle with mozzarella cheese. Remove from the heat and cover for 2-3 minutes or until cheese is melted.
Meanwhile, in a small saucepan, combine tomato sauce and basil; cook until heated through. Serve with chicken. Yield: 6 servings.
