1. Preheat the oven to 350 degrees.
2. Grind the garlic and spicebush berries together in a food processor or chop them fine by hand. Add the remaining ingredients, except the bread crumbs, and process until the beans are mashed, or mash the ingredients together in a large bowl with a potato masher or fork. Mix in the bread crumbs.
3. Shape the mixture into patties and bake the patties on an oiled cookie sheet for 30 minutes, or cook them in an oiled frying pan with a raised grill until the patties are lightly brown, about 10 minutes on each side.
