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

Add cooked quinoa, chopped onion, minced garlic, bread crumbs, cumin, smoked paprika, salt, and pepper. Mix until well combined.

Form the mixture into 4 equal patties.

Heat olive oil in a skillet over medium heat.

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

If using cheese, place a slice on each patty during the last minute of cooking to melt.

Toast the burger buns if desired.

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

Serve immediately and enjoy!
