In a large bowl or in the food processor, add black beans, quinoa, onion, green pepper, Worcestershire sauce, garlic, cumin, dried oregano, smoked paprika, chili powder, salt, pepper, egg (or flax egg), and panko breadcrumbs.
Mash with a fork or pulse the mixture a few times in the food processor until desired texture.
Using your hands, form 6 patties and place in the fridge for 5 minutes.
In a skillet, heat olive oil at medium high heat. Cook patties in batches for 5 minutes on each side.*
Serve black bean burgers on toasted hamburger buns with toppings and/or mango salsa. Enjoy!
* If you'd like to make these in the oven, you can bake them on a lined baking sheet at 400ºF for 10 minutes, flipping over halfway for another 10 minutes.
