Drain, and rinse, the black beans. Place them in a bowl and use a fork to mash them. Keep mashing until they're mostly broken up, but still have some whole beans visible. Add the breadcrumbs, onion, egg, corn, taco seasoning and salt, pepper. Stir until everything is combined, then let the mixture sit for 5 minutes.
Using a ½ cup measuring cup divide the mixture and make
into patties. You can pan fry them in safflower oil 5 minutes per side or you can bake them in a 375 degree oven for 10-15 minutes turning once. I like to serve mine on a whole wheat slicer bun with fresh salsa and avocado slices.
