Instructions

  1. In a large skillet, brown and crumble the ground sirloin with the chopped onion until no longer pink; drain excess fat, if desired (there shouldn't be that much if you've used the extra lean ground sirloin).
  2. Return cooked beef/onions to skillet. Add the tomato sauce, water, diced tomatoes, dry macaroni and seasonings. Stir well and bring to a boil.
  3. Reduce heat to medium-low. Cover tightly and simmer for 12-15 minutes (stirring once or twice) or until macaroni is tender.
  4. Add milk and cheese and stir well, until cheese is smooth and melted.
  5. Serve.
