Black Bean Burgers

Here's a video that might be helpful, from the Food Network.

Ingredients
1/2 medium yellow onion, quartered
1 tablespoon garlic, halved
2 (15-ounce) cans black beans, rinsed and drained, divided
2 tablespoons freshly chopped cilantro leaves
2 teaspoons freshly chopped parsley leaves
1 egg
1/2 teaspoon red pepper flakes
1/2 cup bread crumbs
Salt and fresh ground black pepper
4 hamburger rolls
Optional Toppings:
1 tomato, sliced
4 small Romaine lettuce leaves, or any other type you have on hand
1/4 cup ketchup
Directions
Heat a grill or grill pan over medium-low heat.

In a food processor, make bread crumbs. Remove. Add onion and garlic to food processor 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 four five 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.
