Janelle's Black Bean Soup

1 onion, chopped

1 T cumin

3 cans black beans

3 c salsa

1 can chicken broth

In a blender, combine 2 cans black beans, chopped onion, and chicken broth. (Keep the juice from the beans if you want a thinner soup, otherwise just add the beans.) Put blended mixture into a large pot. Add salsa, cumin, and remaining can of beans. Bring to a boil then reduce heat and simmer for 30 minutes. Serve with tortilla chips.
