1 lb. hamburger
2 med. onions, chopped (about 1 c.)
1 (28 oz.) can whole tomatoes
3/4 c. chopped green pepper
1/2 c. water
1 (4 oz.) can mushroom stems and pieces, drained
2 tsp. salt
1 tsp. sugar
1 tsp. chili powder
7 oz. uncooked thin spaghetti, broken into pieces
1 c. shredded cheddar cheese (about 4 oz.)

Cook and stir hamburger and onions in 10-inch skillet or Dutch oven until hamburger is light brown; drain. Stir in tomatoes (with liquid), green pepper, water, mushrooms, salt, sugar, chili powder and spaghetti. Break up tomatoes with fork.

Heat to boiling; reduce heat. Cover and simmer, stirring occasionally, until spaghetti is tender, about 30 minutes. (Add water during cooking if necessary.) Sprinkle with cheese. Cover and heat until cheese is melted.
