1 lb. dried beans, soaked overnight
4 c. cold water
1 lg. onion, coarsely chopped
1 (16 oz.) can tomatoes
2 garlic cloves, minced (at least this amount)
1 tsp. crushed red pepper or 2 tsp. chili powder
2 tsp. salt
1/4 lb. salt pork or bacon, chopped (optional)
2 tsp. cumin

Put all ingredients into crockery pot (slow cooker). Cook on high for 2 hours, then low for 8 hours. The beans can then be partially mashed for a low-fat alternative to refried beans.
