Prepare stuffing according to package directions. In a mixing bowl combine ground beef and milk. Divide mixture into five meatballs. Roll into thin patties. Place 1/5 of stuffing in center of patty, then draw meat over stuffing and seal. Place meatballs in baking dish. Cover with Saran Wrap and freeze or refrigerate.
To serve, combine soup with 1/4 cup water. Pour over meatballs. Bake frozen meatballs, uncovered in 350 degree oven for 1 hour or cook in microwave oven 8 to 10 minutes on full power by loosening one corner of Saran Wrap to form a vent for steam to escape. Serves 5.
