01 - Heat 1 tablespoon of olive oil in a skillet over medium heat. Add the chopped onion, grated carrot, and diced bell pepper. Sauté for 3 to 4 minutes until the vegetables are softened. Stir in the minced garlic and cook for 1 additional minute until fragrant. Remove from heat and let cool slightly.
02 - Place the drained and rinsed black beans in a large mixing bowl. Using a fork or potato masher, partially mash the beans, leaving some chunks intact for a hearty texture.
03 - Add the sautéed vegetable mixture, rolled oats, breadcrumbs, egg, smoked paprika, ground cumin, salt, black pepper, and chopped parsley to the mashed beans. Stir until all ingredients are evenly incorporated. If the mixture is too wet, sprinkle in additional breadcrumbs. If too dry, add a splash of water to bind.
04 - Divide the mixture into 4 equal portions and shape each into a firmly packed burger patty, approximately 3/4 inch thick.
05 - Heat the remaining 1 tablespoon of olive oil in a skillet over medium-high heat. Carefully place the patties in the pan and cook for 4 to 5 minutes per side until golden brown and heated through. Alternatively, grill the patties over medium heat for a smoky char.
06 - Toast the burger buns if desired. Layer each bun with a cooked patty and your choice of lettuce, tomato slices, pickles, onion, cheese, and condiments. Serve immediately while hot.
