Make the Have-it-Your-Way Chipotle BBQ Sauce if you don't already have some on hand (see step 8).
Heat 1 teaspoon of olive oil in a medium skillet on medium heat**. Add the onion and poblano pepper and cook, stirring frequently, until the onion is soft and translucent, approximately 5 minutes.
Drain the beans (reserve the liquid) and rinse well. Put 2¼ cups (140 g) of the beans in a food processor and pulse until they're creamy. Scrape the beans into a mixing bowl and add the remaining whole beans. Add the onion and peppers, cornmeal, oat flour, aquafaba, 3 tablespoons (45 ml) of BBQ sauce, salt and pepper to the bowl and stir until combined.
Scoop a ½ cup (120 ml) of the black bean mixture from the bowl and form into a patty. Continue making patties with the rest of the mixture. Brush a liberal layer of the BBQ sauce on both sides of the burgers.
5. Heat a grill pan or a skillet on medium-high heat and brush with 2 teaspoons (10 ml) of oil. 6. Place the burgers in the pan, cover and cook for approximately 5 to 7 minutes, gently flip and cook for another 5 to 7 minutes.
Even though these burgers hold together well, they're still veggie burgers, and can break apart if you are too rough while flipping.
Put the lettuce on the buns and top with your toppings of choice! Or enjoy Bad to the Bowl style in a vegan bowl!
