Slow Cooker Taco Soup

2 cans of kindey beans; rinsed

2 cans of pinto beans (or black beans); rinsed
2 cans of corn
1 large can of diced tomatoes
1 can tomatoes and chiles (such as Rotel)
1 packet taco seasoning
1 packet ranch dressing mix (optional)
1 lb browned ground turkey or hamburger (optional.)
shredded cheese and sour cream for topping (optional)

Brown meat if you are going to use it.  Drain fat and add meat to crockpot stoneware insert.  Sprinkle seasoning packet(s) on top of meat.  SDain and rinse the beans and add to crockpot.  Add the entire contents of the corn and tomato cans; stir.

Cover and cook on low for 8-10 hours or on high for 4-5. I think the longer you cook soup, the better, so if you have the time, opt for cooking on low. Stir well, and serve with a handful of shredded cheese and a dollop of sour cream.
