Cook the quinoa according to directions, and set aside to cool.
As the quinoa is cooking, heat 2 Tbsp olive oil in a large skillet.
In the skillet, cook the onion and garlic for a few minutes, until beginning to soften.
Add the grated sweet potato and all of the spices. Cook for another 3 minutes.
Remove from heat, and allow to cool enough to handle before continuing.
In a large bowl, whisk together the eggs, breadcrumbs, cheese, and cilantro, then add the cooled quinoa and vegetable mixture. Mix to fully combine.
In a heavy skillet over medium heat, heat more olive oil before adding the batter in small dollops (or shaped into small patties). Cook until golden on each side, about 2 minutes.
Serve on a bed of greens or cabbage, garnished with green onions.
