BEAN BROWNIES

1 regular size Brownie Mix (I used one that fit in a 9x12 pan)
1 (15 1/2 oz) can black beans DO NOT DRAIN
chopped walnuts (optional)

Put black beans in a blender or food processor and blenderize until smooth. In a mixing bowl combine the black beans and brownie mix. Mix well. May stir in chopped walnuts if desired. (No, you don't add water or egg)

Bake the brownies according to the directions on the brownie mix box.
