In a medium-sized bowl, mash some of the black beans to form a paste, leaving some beans whole.
Add the remaining ingredients and stir, mixing well (for best results use hands).
If mixture is too wet to form into shapes, add some more bread crumbs.
Form into 4 large or 6 small patties and bake on a parchment-covered baking sheet at 350 for approximately 20 minutes, flipping over halfway through.
Eat immediately or allow to cool and freeze in a plastic bag or airtight container.
