Refried Beans in the Crockpot

I signed up to take refried beans to the ward taco night, having heard you could make refried beans in the crockpot. They turned out pretty good, and way cheaper than buying cans to warm up. Here is the "recipe"

dry pinto beans
water
beef boullion
salt
onion salt

Sort and rinse pinto beans. Put in crockpot - NOT turned on - overnight to soak, with water a few inches over the beans. In the morning drain beans and put in fresh water, covering beans completely. Cook on low all day (6 hours or so), adding water periodically to keep the beans covered. Use a potato masher or blender to mash the beans. Add beef boullion, salt, and onion salt to taste. We added a little oil to our beans, too. Jim said we should really have some bacon grease or something to make them a little more authentic. But, they turned out pretty good!

I did one full (1 lb?) bag of beans in my larger round crockpot, and the pot overflowed. Next time I will use my big oval crockpot. It made TONS, but you can put it in containers and freeze them for later.
