Crockpot Refried Beans

1/2 onion peeled and halved
 1 lbs of dry pinto beans (no need to rinse or sort or soak)
1/2 jalapeno (remove the seeds for more heat.)
 1 TBSP pressed garlic
1/2 tsp cumin
1/2 TBSP chili powder
  4.5 cups chicken or vegetable broth
1.5 cups water

Directions:
Basically, dump everything into a crockpot and cook on high for about 6-8 hours.  Pour half of the beans and all of the onion chunks into a blender and puree.  Pour the puree back into the crockpot and stir. You can add more water if needed.
