1/3 cup coarsely chopped onion
2 cloves garlic, peeled
1 teaspoon cumin
1 1/2 cups canned black beans (or black soybeans), rinsed and drained
1/2 cup dried bread crumbs
1/3 cup chopped cilantro leaves
3/4 cup walnuts, toasted and finely chopped
1 large egg, beaten
salt and pepper
Directions: In a food processor fitted with a metal blade, place onion, garlic, and cumin; pulse until coarsely chopped. Add beans, and cilantro; pulse until just combined (don’t puree). Transfer mixture to bowl. Add walnuts to food processor and finely chop. Add chopped walnuts and bread crumbs to bean mixture. Season with salt and pepper. Fold in egg and stir until combined. Form into patties. (If burgers seem very wet, add 1/4 cup bread crumbs.) Chill patties, covered, at least 1 hour, and up to 1 day. In a large skillet, heat oil over medium heat until hot; cook patties until light brown, 4-6 minutes on each side. (we usually brush patties with olive oil, and cook on an outdoor grill, or an indoor foreman grill , until heated throughout.
I usually make a double batch and freeze extras for a quick, easy meal.
