Prepare the Black Bean Patties: In a large bowl, mash the rinsed and drained black beans with a fork or potato masher until mostly smooth but still with some texture. Add the breadcrumbs, minced onion, ground cumin, smoked paprika, garlic powder, salt, and black pepper. Mix well to combine. Form the mixture into 4 equal-sized, loose balls, about 1/2-inch thick.
