I thought since everyone was sharing cheap recipes I'd get off my butt and add a few!

3 cups spiral pasta, cooked, drained (still hot)
1 quart spaghetti sauce
1 pound ground beef or Italian sausage, cooked & drained
1 package sliced pepperoni
1 cup grated Parmesan cheese
1/2 pound shredded mozzarella cheese
4 ounce can mushrooms

Mix ground beef, macaroni, spaghetti sauce, mushrooms, pepperoni, and parmesan cheese together.

Place all in a greased 9x13 dish and top with mozzarella cheese.
Bake at 350F for 20 minutes.
