Grandpa Jack called this Macaroni Casserole (Gamm) I've never been quite sure how to spell it.
But this will do, since it's ours. 😊

11/2 lbs. ground beef
2  28-32oz. cans tomatoes (chopped are best)

Instructions

Brown and crumble e ground beef with chopped onion.
Stir in tomatoes.
While simmering, cook macaroni (according to package directions)
Drain and add to meat & tomato mixture.
Turn into casserole dish, and add cheese over top.
Bake at 350 o for about 30 minutes (or until crispy on top).
