This is one of our favorite finds in our vegetarian cookbook! They're not exactly hamburgers, but they make a pretty decent hamburger-like sandwich. (I usually buy dry beans and cook them myself, and then add spices.)
1 can black beans with cumin and chili spices, undrained
1 can chopped green chilies, undrained
1 cup plain dry bread crumbs
1 egg, beaten
1/4 cup yellow cornmeal
2 tablespoons vegetable oil
1. Place beans in food processor or blender. Cover and process until slightly mashed; remove from food processor. Mix beans, chilies, bread crumbs and egg. Shape mixture into 5 patties, each about 1/2 inch thick. Coat each patty with cornmeal.
2. Heat oil in 10-inch skillet over medium heat. Cook patties in oil 10 to 15 minutes, turning once, until crisp and thorougly cooked on both sides.
3. Serve on hamburger buns with toppings of your choice!
