To make the burgers, first gather and prepare all of your mise en place.
The amount of chili powder needed, will depend on how spicy you like your food and how spicy the chili powder is. We used this
Chili Powder recipe, which was a nice balance of flavor and spice.
Next, place a large fry pan over medium heat. Once the pan is hot, dry-sauté the onions until golden and translucent — adding a touch of water to the pan as needed, so the onions and/or pan do not burn.
Next, add the garlic and cook for 30 seconds or so and then add the mushrooms. Let this cook for 5 minutes or so, or until all of the moisture has cooked out of the mushrooms.
At this point, transfer the mushroom mixture to a food processor. Add the quinoa, black beans, oats, spices and flax meal. Pulse the mixture a few times. Do not over pulse the mixture, the texture should course/chunky, but still hold together. Taste the mixture for seasoning and adjust as desired.
Note that these burgers can be made a day or two ahead of time and stored in the refrigerator. They also freeze very well.
