To start, place the quinoa and salt into a medium pot along with the water (or stock) and cook according to the package. Generally, quinoa takes about 15 minutes. Once done, set aside.
Meanwhile, roast the poblano peppers. This can either be done
on the barbecue or
under the broiler. Alternatively, the poblanos can be done right on a gas burner. Once the skin has charred and blistered on all sides, place into a bowl and cover with plastic wrap. When the poblanos are cool enough to handle, peel the skin and remove the seeds. Then dice and set aside.
Next, dice the red onion and mince the garlic. Chop the cilantro and gather the spices, nutritional yeast and cornmeal.
To cook the burger mix, heat a large fry pan over medium-low heat. Add the oil, followed by the onions, as well as a good pinch of salt. Once the onions are soft and translucent, add the garlic and cook for another 30 seconds or so. Next add the spices and cook for another 30 seconds. Add the cooked beans, stirring to combine and then turn off the heat.
Next, mash the beans until quite smooth. A potato masher or a pastry cutter work well for this. If you don't have either of these, a fork will also work. If your fry pan is big enough, you can finish mixing the burgers right in the fry pan. If it isn't, transfer the mixture to a large bowl before you continue. To finish, add the quinoa, poblano peppers, cilantro, nutritional yeast and cornmeal. Mix everything to combine.
