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

Add cooked quinoa, chopped onion, minced garlic, grated carrots, cumin, paprika, bread crumbs, and beaten egg. Mix until well combined.

Season with salt and pepper to taste.

Divide the mixture into 4 equal portions and shape each into a patty.

Place the patties on a baking sheet lined with parchment paper.

Heat a skillet over medium heat and add a little oil.

Cook the patties for about 5-7 minutes on each side, or until golden brown.

Toast the burger buns if desired.

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