Ingredients

• 1/2 cup walnuts
• 1/2 cup rolled oats
• 1 tablespoon flax seeds
• 1 teaspoon ground cumin
• 1 teaspoon paprika
• 1 teaspoon salt
• 1 pinch ground cinnamon
• 2 (15 ounce) cans black beans, rinsed and drained
• 1/2 cup mashed cooked sweet potato
• 1 egg, beaten
• 1/4 cup minced onion
• 1 Fresno chile pepper, seeded and minced
• 1 small crimini mushroom, minced
• 3 cloves garlic, minced
• 1/2 teaspoon soy sauce
• 1/2 cup vegetable oil

Instructions

1. Process walnuts in a food processor until you have a coarse powder; add oats, flax seeds, cumin, paprika, salt, and ground cinnamon and process again until the oats are ground into a coarse powder. Put black beans and sweet potato into the processor bowl; process until smooth and transfer to a mixing bowl.
2. Stir egg, onion, Fresno chile, crimini mushroom, garlic, and soy sauce into the black bean mixture until smoothly integrated; shape into 6 patties.
3. Heat vegetable oil in a skillet over medium-high heat until shimmering. Fry patties in oil until a deep-brown crust forms, about 5 minutes per side.
