Black Bean Soup

This is what I had for lunch today and it was yummy! It was my first time making it and it turned out great.

1 can whole black beans
1 can broth (chicken, beef or vegetable)
1Tbs butter
1/2 small onion (chopped)
1 garlic clove (chopped)
sour cream (optional)
salt and pepper to taste

Saute the onion and garlic in butter. Than place 3/4 of the can of beans and the whole can of broth in a blender and blend until smooth. Add the mixture to the pan with the onions, garlic and remaining beans and than bring to a boil. Salt and pepper to taste.
Optional: Top with shredded cheese or sour cream.

Note: For a thick and creamy black bean soup use less broth, blend all of the ingredients together and stir in a spoonful of sour cream.
