Prepare 2 boxes Kraft Macaroni and Cheese according to directions on box.

Brown 1 pound hamburger or sausage (or 1/2 pound of each) and drain well.

Put prepared macaroni and cheese in a 13x9 pan. Pour 1 can Chef Boy R Dee pizza sauce over macaroni and cheese. Top with meat (pepperoni, sausage, hamburger, Canadian bacon). Add any other topping (green peppers, mushrooms, etc.). Spread one 8 ounce package of shredded Mozzarella cheese over top. Bake for about 5-8 minutes at 350 degrees until cheese is melted thoroughly. Cool slightly and serve in squares.
