1 16-ounce can black beans, drained
1 16-ounce can white beans, drained
1 large egg
4 garlic cloves, minced
1 teaspoon Cajun seasoning
2/3 cup sour cream
1 avocado
10 medium basil leaves
1 cup panko
2 tablespoons olive oil
6 hamburger buns
Preheat the oven to 400 degrees
Combine the beans, egg, garlic, and Cajun seasoning in a food processor. Process until relatively smooth but some chunks still remain. Set the mixture aside in a bowl.
Rinse out the food processor and add the sour cream, avocado, and basil. Process until smooth and place in a serving dish.
Form the bean burger mixture into patties and dredge in panko.
Brush the burgers with olive oil on both sides and set on a nonstick baking sheet. Bake for 20 minutes, or until cooked through and crispy on the outside.
Toast the hamburger buns. Serve each burger on a bun with a dollop of avocado sauce.
