Preheat oven to 350°F.
Cook mac and cheese according to box instructions. Sauté onions and beef until browned. Mix together baked mac and cheese, beef mixture, and tomatoes and put in a stew dish. Cover and prepare in a oven for 30 to 60 minutes. (Depends on how desirous we are. we like it baked longer so a tip covering of noodles gets crispy!)
we infrequently will supplement peas too. And infrequently I’ll supplement a cut of American cheese on tip afterwards x-ray it!
