Burger Patty

Toppings

Spicy Mayo

Method

Prepare the Burger Patty

  1. 1

    Mash the Black Beans

    In a large bowl, mash the black beans with a fork or potato masher until mostly smooth, leaving some chunks for texture.

  2. 2

    Combine Ingredients

    Add the chopped mushrooms, grated yellow squash, bread crumbs, garlic powder, onion powder, cumin, salt, and black pepper to the mashed beans. Mix until well-combined.

  3. 3

    Form Patties

    Divide the mixture into 4 equal portions and form into patties. If the mixture is too wet, add more bread crumbs until it holds together.

  4. 4

    Cook Patties

    In a skillet, heat olive oil over medium heat. Cook the patties for about 5-7 minutes on each side, or until golden brown and heated through.

Prepare Toppings

  1. 5

    Wash Lettuce

    Rinse the lettuce leaves under cold water and pat them dry with a paper towel.

  2. 6

    Slice Tomato

    Slice the tomato into even rounds for easy layering on the burger.

  3. 7

    Prepare Fried Onions

    If using store-bought fried onions, measure out the desired amount. If frying your own, slice onions thinly, coat them in flour, and fry in oil until golden brown.

  4. 8

    Slice Roasted Peppers

    If using jarred roasted red peppers, drain and slice them into strips.

Make Spicy Mayo

  1. 9

    Mix Mayo and Sriracha

    In a small bowl, combine mayonnaise and Sriracha sauce. Stir until well blended. Adjust the amount of Sriracha to taste for desired spiciness.

Assemble the Burger

  1. 10

    Layer Ingredients

    On the bottom half of a burger bun, place a lettuce leaf, followed by the burger patty, sliced tomato, fried onions, and roasted red peppers.

  2. 11

    Add Top Bun

    Finish with the top half of the burger bun. Serve with spicy mayo on the side for dipping.
