In a large bowl add black beans and mash against the side of the bowl with a fork until all beans are thoroughly mashed. Add the remaining ingredients and stir well. Shape bean mixture into 4 patties, place on a plate, cover and refrigerate for 1-2 hours.
Lightly spray the bottom of a skillet with cooking spray, heat to medium-low, add the bean patties and cook approximately 15 minutes or until heated through. Serve on buns with your favorite trimmings.
