Ingredients

2 (14-ounce) cans black beans, rinsed and drained, divided

3 tablespoons mayonnaise

1/3 cup plain dry bread crumbs

2 teaspoons ground cumin

1 teaspoon dried oregano, crumbled

1/4 teaspoon cayenne

1/4 cup finely chopped cilantro

3 tablespoons vegetable oil

4 soft hamburger buns

Preparation

Pulse 1 can beans in a food processor with mayonnaise, bread crumbs, cumin, oregano, and cayenne until a coarse purée forms. Transfer to a bowl and stir in cilantro and remaining can beans. Form mixture into 4 patties.

Heat oil in a 12-inch heavy skillet over medium-high heat until it shimmers. Cook burgers until outsides are crisp and lightly browned, turning once, about 5 minutes total. Serve on buns.
