  1. Preheat the oven at 400F. And line a baking sheet with parchment paper.

  2. Cook the quinoa according to package directions and allow to cool.
  3. In the bowl of a food processor, add the walnuts, onion, and garlic. Process until finely minced.
  4. Add the cumin, chili, sea salt, hot sauce, egg, 1/2 cup of the quinoa, and 1 cup of black beans. Process until almost smooth.
  5. Add the mixture to the bowl and fold in the remaining quinoa, black beans, and flour. The mixture may be wet, that is normal.
  6. Using a 1/3 cup measuring cup lined with cling wrap, form burgers. Using the bottom of the measuring cup, lined with cling wrap, lightly press down on the burgers to flatten a little.
  7. Bake for 40 minutes, flipping halfway through. If sweet potato fries are still cooking, then these can go in the same oven on the lower rack.

  8. Assemble your burgers to your pleasure and enjoy!
