In a mixing bowl, mash the black beans with a fork or potato masher until mostly smooth.

Add cooked quinoa, bread crumbs, grated carrot, diced bell pepper, minced garlic, cumin, paprika, salt, and pepper. Mix until well combined.

Shape the mixture into 4 equal patties.

Heat olive oil in a skillet over medium heat. Cook the patties for about 5-6 minutes on each side until golden brown.

Place each patty on a bun and top with lettuce, tomato, pickles, and any additional toppings you prefer.
