This vegan black bean burger is a tasty and satisfying alternative to traditional burgers. To make it, start by mashing some black beans in a bowl. Add some diced onion, minced garlic, breadcrumbs, and your favorite spices (such as cumin, chili powder, or smoked paprika). Mix well, and form into patties. Cook on a grill or in a pan until lightly browned on both sides. Serve on a bun with your favorite toppings (such as avocado, tomato, or lettuce) for a delicious meal.
