Prepare the Beans - Reserve 6 tablespoons of the liquid from the black beans and place in a medium bowl, set aside. Line a baking sheet with three layers of paper towels. Rinse the beans using a colander, then shake off any excess moisture and evenly spread across the paper towels. Allow them to dry while preparing the other ingredients.
Make the Seasoning Mixture - Add the flour to the bowl with the bean liquid and whisk until smooth. Add green onions, cilantro, garlic, cumin, coriander, chili powder, smoked paprika, salt, and pepper and stir to combine. Set aside.
Process the Chips and Beans - Add chips to a food processor and process on high speed until finely ground, about 30 seconds. Add the dried black beans and pulse until coarsely ground, about 5 pulses.
Form the Patties - Add the black bean mixture to the bowl with the seasoned flour mixture. Stir to combine. Measure out ½ cup and form and flatten it into 4-inch wide patties. Makes 5 black bean burgers.
Cook the Patties - Heat a 12-inch nonstick skillet over medium heat. Add 1 tablespoon of oil. Once hot, add in 3 patties and cook until browned and lightly crisp, about 5 minutes.Flip the patties and add 1 tablespoon of oil. Cook until the other side is browned and crisp, about 3 to 5 minutes. Repeat the cooking process with the remaining two patties and 2 tablespoons of oil.
To Serve - Add the burger patties to the buns and add desired toppings.
