Step 1

Preheat the oven to 325 degrees.

Step 2

Spread beans on a lined baking sheet and bake for 15 minutes until slightly dried out. Reserve ½ cup black beans.

Step 3

In a food processor, combine the remaining beans, lime, onion powder, garlic powder, cumin, and parsley. Pulse until mixture comes together. Remove from processor and set aside.

Step 4

In a food processor, combine poblano, onion, oats, and walnuts. Pulse a few times until you reach your desired consistency. I prefer a chunky texture, so I only pulse a couple of times.

Step 5

In a large bowl, combine the bean mixture, oat mixture, the reserved ½ cup black beans, salt, and pepper. Stir until well combined.

Step 6

Using a large cookie or ice cream scoop, scoop the mixture, and form into patties. I used 2 scoops per patty. Place patties on a parchment or waxed paper-lined tray and freeze for one hour.

Step 7

In a non-stick or cast-iron skillet, heat 1 tbsp olive oil over medium heat. Place two frozen patties in a skillet and cook for approximately 4 minutes on each side. Cook remaining burgers, adding a little oil each time.

Step 8

Assemble with desired toppings/bun and serve.
