15-Minute Black Bean Burgers

1.Heat olive oil in a non-stick skillet over medium heat.

2.Place black bean patties in the hot skillet. Cook for 4-5 minutes per side, or until heated through and lightly browned. If using cheese, place a slice on each patty during the last minute of cooking and cover the skillet to melt.

3.While the patties are cooking, lightly toast the burger buns. You can do this in a toaster, under a broiler, or in a separate dry skillet.

4.Spread mayonnaise on the bottom half of each toasted bun and ketchup on the top half.

5.Assemble the burgers: place a lettuce leaf on the bottom bun, followed by a cooked black bean patty (with melted cheese, if using), tomato slices, and red onion slices.

6.Top with the other half of the bun and serve immediately.
