Taco Beef Soup

Another recipe from "The Essential Mormon Cookbook". I have had a taco soup that my mother-in-law made and it was really good. I can't remember if this has the same stuff but it sounded pretty good.

1 lb ground beef
1/2 c. chopped onion
3 c. water
1 (26 oz) can stewed tomatoes, undrained
2 (16 oz each) cans kidney beans, undrained
1 (16 oz) can tomato sauce
1 (1.5 oz) envelope taco seasoning mix
cheddar cheese, grated
tomatoes, chopped
green onions, chopped
corn chips
sour cream
avocado, chopped

In a large saucepan cook ground beef and onion until meat is browned; drain off excess fat. Add the water, stewed tomatoes, kidney beans, tomato sauce, and taco seasoning. Simmer, covered, for at least 15 minutes. Pass cheese, tomatoes, green onions, corn chips, sour cream, and avocado for each person to top their individual serving. Makes 6 servings.
