1 lb. hamburger
1 can condensed tomato soup
4 hamburger buns

4 slices American cheese

Brown hamburger and onions together, drain excess fat. Add tomato soup and let simmer. Place each half of bun on a cookie sheet. Top each with beef mixture and 1/2 slice cheese. Bake at 350 degrees for 15 minutes. This is a quick and easy item. The kids love 'em.
