If you have never made burger patties, these are the ones you want to make first. With a simple list of ingredients—such as beans, walnuts, oats, and spices—you can kick-start your veggie burger adventure here. Serve with your favorite burger fixings.
In a food processor, combine the walnuts, oats, garlic, ginger, onion, and jalapeños and pulse a few times, until the walnuts and onions are evenly chopped, 5 to 10 seconds. Add the beans, cilantro, cumin, oregano, chili powder, salt, pepper, and flax seed and process in 5-second intervals, until most of the beans break down. Do not puree—there should still be some whole beans for texture.
Transfer the mixture to a bowl. Cover the bowl and chill for 15 minutes. If the mixture is too wet, add the breadcrumbs and stir to combine.
Divide the mixture into 7 to 8 equal portions. Shape into tightly packed patties. Heat a large skillet over medium-high heat (add oil if desired). Place the patties in the skillet and cook for 4 to 6 minutes per side, or until golden brown. Alternatively, preheat the oven to 400°F (200°C). Place the patties on a medium baking sheet lined with parchment paper. Bake the burgers for 15 minutes, flip, and bake another 10 minutes, or until the burgers are golden.
