Step 1

Oven: Preheat oven to 375°F (190°C). Line a baking sheet with parchment paper and set aside.

Step 2

Prepare patties: In a large food processor, add walnuts and oats. Pulse until a medium-fine crumble forms. Dice onion and add to food processor. Then add all other seasonings & ingredients except black beans. Pulse/blend to combine, scraping down sides if needed.

Step 3

Add beans: Rinse and drain black beans. Gently pat dry with a paper towel to remove excess moisture. Add beans to food processor. Pulse a few times to incorporate. (The mixture will be very dense, and it's okay to leave the beans chunky.) It takes a little patience, and you may have to stop a few times to scrape down the sides with a spatula to help encourage the mixture. (If you don't think your food processor can handle this, slightly mash the beans in a separate bowl. Then add the pulsed walnut/oat/spice mixture to the mashed bean bowl and stir well to combine.)

Step 4

Shape: Carefully remove the S-blade from your food processor. Then scoop out the mixture into 5 even balls. Shape into patties, and place on lined baking sheet. (For me, the mixture is about 1.4lbs. So I measure out five heaping "quarter pounders" of .28lbs each.)

Step 5

Bake: Place in oven and bake for 15 minutes. Flip the patties, then bake 15 more minutes. Let rest 5-10 minutes before serving to firm up even more if desired. Assemble burgers on buns topped with BBQ sauce or other toppings of choice.
