In a large bowl, using a fork, mash half of the black beans. Add remaining beans. In a small bowl, mix dry spices together. Pour dry spices over bean mixture. Add all of the remaining ingredients and mix well with hands. Form into 4-5 burger patties. Bake them in a lightly oiled pan at 350 degrees F for about 20 minutes or until browned. Serve with sweet potato fries and a side salad.
