Beefaroniesque, an idea from Karli

Last night I tried something that turned yummy. I had some leftover mac & cheese and mixed it with a pound of browned ground beef, a can of diced tomatoes with onions, and seasonings (oregano, basil, garlic, etc.). I put it in a pie plate, covered with mozzarella and cheddar cheese and baked at 350° until the cheese was melted.
