Soak your beans over night. In the morning drain and throw out pebbles and hard things. Place in crockpot with enough water to cover and then About an inch. Dump in garlic and cumin and quartered onion (if you have it). Cook on low for 8 hours or until beans are soft. You can either eat the pintos whole or mash for burritoes. Discard onion before mashing. Some people mash using oil. I just mash with a little water. (They will look dry but taste fine without added fat) Serve as burritoes or nachos. Yummy, easy and so cheap.
