So this is by no means a substitute for a good beef hamburger, but not a bad sandwich for Meatless Mondays.
1/2 medium yellow onion, roughly chopped
1 tablespoon chopped garlic
2 (15-ounce) cans black beans, rinsed and drained, divided
2 tablespoons freshly chopped cilantro leaves
2 teaspoons freshly chopped parsley leaves
1/2 teaspoon red pepper flakes
1/2 cup bread crumbs
Salt and fresh ground black pepper
4 hamburger rolls
1 tomato, sliced
4 small Romaine lettuce leaves, or any other type you have on hand
1/4 cup ketchup
Heat a grill or grill pan over medium-low heat.
In a food processor, pulse onion and garlic until finely chopped. Add 1 can black beans, cilantro, parsley, egg, and red pepper flakes and pulse to combine.
Transfer mixture to a large mixing bowl, add the remaining can of black beans and the bread crumbs. Season with salt and pepper, to taste, and mix until well combined.
Reserve 1/3 of the black bean mixture for Round 2 Recipe. Divide remaining mixture into 4 portions and form into patties. Place on hot oiled grill over medium-low heat and cook about 6 minutes a side or until heated through. Toast hamburger buns on a grill. Place a burger on the bottom of each bun. Top with lettuce, tomato and ketchup. Cover the burgers with the top of the bun and serve.
