Laura's Slow Cooker Taco Soup

INGREDIENTS: 1 pound ground beef
1 onion, chopped
1 (16 ounce) can chili beans, with liquid
1 (15 ounce) can kidney beans with liquid
1 (15 oz) black beans with liquid
1 (15 ounce) can whole kernel corn, with liquid
1 (8 ounce) can tomato sauce
2 cups water
2 (14.5 ounce) cans peeled and diced tomatoes
1 (4 ounce) can diced green chile peppers
1 (1.25 ounce) package taco seasoning mix

DIRECTIONS:
In a medium skillet, cook the ground beef until browned over medium heat. Drain, and set aside.  Saute onions.

Place the ground beef, onion, chili beans, kidney beans, corn, tomato sauce, water, diced tomatoes, green chile peppers and taco seasoning mix in a slow cooker. Mix to blend, and cook on Low setting for 8 hours. My sister, Laura also sometimes adds a can of rotel tomatoes. (they are tomatoes mixed with chilies. This would make the soup a bit hotter) Also, Laura uses the frozen costco super sweet corn instead of canned.
We have also recently made it without meat to save calories and it's still good.  At times you are less concerned about calories, it is delicious with a little sour cream and crunched up corn chips added when serving.
