About 6 oz. ABC's macaroni, or O's (These are very small and any type of very small macaroni product would do.)
1 qt. water and 1/2 tsp. salt. Bring to a boil and cook macaroni until done. Do not drain.
1 or 2 cans tomato soup, depending upon your preference. Add to macaroni and mix. (You can often buy tomato soup at the discount stores very cheaply.)
4 oz. (approx.) American cheese or processed cheese food, like Velveeta. You can add more or use less.
Heat through only until cheese melts.
