1 (8 ounce) box macaroni and cheese mix (with the powdered cheese)
1 (15 ounce) can diced tomatoes
2 cups milk
1/2 cup butter or 1 cup margarine
salt and pepper
1 small onion (diced)
water, as desired

Preparation

Cook onion and tomatoes together until onion is tender (add water if need to finish cooking process).
Cook macaroni noodles until tender (as directed on box).
Drain and mix with tomato and onion.

Add water to achieve desired thickness (this cooks up real thick, so I usually add a couple of cups).
