Step 1

Place one can of black beans in a food processor and pulse a few times to mash the beans but leave them slightly chunky. Pour this mixture into a mixing bowl. Add the remaining ingredients and stir to combine.

Step 2

Heat a cast iron skillet to medium-high and add enough oil to coat the bottom of the pan.

Step 3

Form patties out of the veggie mixture. Place patties on the hot skillet and cook until the sides begin to firm up, about 3 to 4 minutes.

Step 4

Carefully flip the patties and cook until the patty is firm when poked. Both sides of the patty should be crisp.

Step 5

Toast hamburger buns cut-side up in the oven on broil. Add your favorite toppings to the burger, such as avocado slices, tomato, red onion, etc.
