Ingredients
8 servings
- •1 (16 ounce) package cremini mushrooms, cut in half
- •0.5 small onion, chopped
- •3 tablespoons olive oil, divided
- •1 (15 ounce) can black beans, rinsed and drained
- •1 (8.8 ounce) pouch cooked brown rice, cooled
- •0.5 cup walnuts
- •1 tablespoon Worcestershire sauce
- •1 tablespoon ketchup
- •2 teaspoons soy sauce
- •1 teaspoon garlic powder
- •1 teaspoon smoked paprika
- •1 teaspoon chili powder
- •0.5 teaspoon kosher salt, or more to taste
- •0.5 teaspoon ground black pepper, or more to taste

Instructions
- Preheat the oven to 450 degrees F (230 degrees C). Line a rimmed baking sheet with foil.
- Place mushrooms and onion on the prepared baking sheet. Drizzle with 1 tablespoon oil and toss to coat.
- Roast in the preheated oven for 10 minutes. Reduce heat to 425 degrees F (220 degrees C) and add black beans to the pan. Cook until mushrooms and onions are browned and beans are dried on the surface, about 5 more minutes.
- Remove from the oven and let mixture cool for 10 minutes.
- Transfer mixture to a food processor. Add rice and walnuts and pulse until roughly chopped. Add Worcestershire sauce, ketchup, soy sauce, garlic powder, paprika, chili powder, 1/2 teaspoon salt, and 1/2 teaspoon pepper and pulse until just combined. Add egg and pulse until just combined.
- Transfer mixture to a medium bowl and fold in bread crumbs until well mixed. Chill for 10 minutes.
- Form mixture into 8 patties and season each with salt and pepper.
- Heat 1 tablespoon oil in a large skillet. Add 4 patties and cook, undisturbed, until browned and a nice crust has formed, about 4 minutes. Flip and cook until done, 4 to 5 more minutes. Top with Muenster cheese and place on toasted buns.
- Add remaining 1 tablespoon oil to the skillet and repeat to cook remaining patties.
