Another recipe from Miss Betty's* Daily Diary Cookbook
1 small onion
2 Tbs. shortening
1 pound hamburger
1 can tomato soup
1 tsp salt
1/2 tsp pepper
1 tsp. chili powder
1 cup grated cheese
Chop onion and cook in melted shortening along with hamburger until meat is rich brown. Stir in tomato soup, salt and pepper and chili powder. Cover and cook slowly for a half hour. Stir occasionally.
At the end of the cooking time, add grated cheese and stir until well mixed. Cut hamburger buns in half, toast until crisp and spoon the hamburger on top.
