It doesn't matter if you're a strict vegetarian or dedicated meat eater, you'll love this recipe for black bean burgers! A veggie alternative, black bean burgers taste just as juicy as a regular hamburger. Consisting only of black beans, an egg white, bread crumbs, green onions and corn, they're easy to assemble, too. Once the patties are heated on the grill, serve them to family and friends at your next cookout on toasted hamburger buns with familiar toppings like lettuce, tomatoes and onions. You can even add a few fresh avocado slices and a dollop of spicy salsa if you're feeling adventurous.
