Step 1

Load up your food processor with the walnuts, chopped onion, garlic, and mushrooms. Pulse until you have a coarsely but evenly chopped mixture.

Step 2

Heat a sauté pan over medium-high heat and add a teaspoon of oil. Transfer the mushroom walnut mixture to the pan, and fry, while stirring, for 7-9 minutes. While that’s cooking, grind the black beans in the food processor until they are coarsely chopped.

Step 3

Remove the pan from the heat and allow the mixture to cool for several minutes before stirring in the bread crumbs, the chopped black beans, the Worcestershire sauce and the egg substitute. Mix well to combine, and chill the burger mixture for 20 minutes to an hour.

Step 4

Divide the mixture into six portions, and form into patties. You might need to wet your hands for this part so the mixture doesn’t stick to your hands.

Step 5

Add a drizzle of oil to a large nonstick or cast-iron pan or griddle, and heat over medium-high. When the pan is hot, lay the patties into the pan (be careful not to splash hot oil on yourself). Cook for 4-5 minutes on one side, then flip them and cook for another 3-4 minutes.

Step 6

Dress up your bun of choice with whatever toppings you fancy, and you’ve got burgers!
