Taco Soup - Weight Watchers

1 lb. ground beef (or turkey)
1 onion (diced)
1 can pinto beans
1 can black beans
1 can chili beans
1 can diced tomatoes
1 can Mexican diced tomatoes
1 pouch ranch dressing mix
1 pouch taco seasoning
1 can corn

***IMPORTANT - DO NOT DRAIN ANY OF THE CANS BEFORE DUMPING THEM IN THE CROCKPOT!

Serve with any combination of the following:
Tortilla chips
Grated cheese (Mexican or cheddar)
Sour cream 
Avocado
Olives

Brown the beef and add the onion to cook for 2ish minutes.  Meanwhile, dump all the cans of beans and tomatoes into a crockpot.  Add the beef and onion.  Add the ranch mix and taco seasoning and stir.  Cook on high for 4ish hours or low for 6ish hours.  Add the corn in the last hour (or if you know you'll forget that step, go ahead and add it at the beginning--I do).
