By margiekyle

Ingredients

• 2 15-oz. cans black beans, drained and rinsed
• 1/2 medium yellow onion, chopped
• 2 cloves garlic, minced
• 1 large egg
• 1/2 c. plus 2 tbsp. mayonnaise, divided
• 3/4 c. panko bread crumbs
• kosher salt
• Freshly ground black pepper
• 2 tbsp. canola oil
• 4 slices white cheddar
• 3 tbsp. ketchup
• 4 Hamburger buns
• 1 tomato, sliced
• 4 Romaine lettuce leaves

Preparation

Step 1

In a food processor, pulse black beans, onion, and garlic until finely chopped.
Transfer to a large bowl and combine with egg, 2 tablespoons mayo, and panko. Season generously with salt and pepper and form the mixture into 4 patties. Refrigerate until firm, about 15 minutes.
In a large skillet over medium heat, heat oil. Add patties and cook until golden and warmed through, about 5 minutes per side.
Top each patty with a slice of cheese and cover the skillet to melt.
In a small bowl, whisk together ketchup and remaining mayo. Spread mayo mixture onto the bottom of the buns, then add burgers. Top with tomato, lettuce, and remaining bun halves.
