This is a basic black bean dip, enjoyed by my children and their friends. In my house, the simpler the recipe, the more the children are bound to try and enjoy it. The "chunky stuff" in a dish tends to not go over well. To add more of a kick to it for adults, you can add cayenne pepper, chopped fresh tomato, chopped avocado, and/or chopped red pepper. Serving size is based on this being an appetizer.
