Coat an 8x8x2-inch (2-quart square) baking dish with cooking spray. Set aside.
In a large bowl, combine meat, cracker crumbs, milk, onion, and parsley flakes. Mix well with your hands. Shape meat into 4 patties. Place patties in prepared dish.
In a small bowl, combine gravy, catsup, Worcestershire sauce, and pepper. Spoon the gravy mixture evenly over meat patties.
Cover and bake in a 350 degree F oven about 1 hour or until done (165 degree F). Serve patties topped with gravy. Serve with noodles, if you like. Makes 4 servings.
