1 lb. pinto or black beans
1 (8 oz.) can tomato sauce
1 tbsp. chili powder
1 tbsp. cumin
1 tbsp. garlic powder
1 tsp. salt, or more to taste
1 chopped onion
1/2 tsp. crushed red pepper flakes

Cover dry beans with water and bring to boil briefly. Let stand at least 1 hour at room temperature before adding remaining ingredients and cook 1-2 hours until tender. Beans may be eaten as they are or may be pureed in food processor to be used as refried beans in tacos, on nachos, in buritos, as dip for chips or spread on bread. For more spicy flavor, add jalapeno chilies or Picante sauce to food processor as you puree the beans.
