 grate the onion, add it, and the garlic, and the beef to the pan over medium heat. Cook it until no pink remains. Then add everything else in, bring it to a boil, reduce it to low, and let it cook for 11 to 13 minutes covered. Every now and again, give it a little stir until that macaroni is cooked through. Then stir in the cheese and serve it hot. Maybe with a nice, cool side salad and a piece of pie. Ooh! Piece of pie! Yeah! Piece of pie!
