Preheat oven to 400 degrees F. In a large skillet cook beef until no longer pink, stirring frequently. Drain off fat. Stir in tomato sauce; heat through. Transfer mixture to a 2-quart rectangular baking dish. Sprinkle mixture with cheese.
Flatten each biscuit with your hands; arrange the biscuits on top of the cheese. Bake in the preheated oven about 15 minutes or until biscuits are golden. Makes 5 servings.
