I am constantly on the hunt for the perfect veggie burger. I've had multiple failed attempts in which the flavors are not right or the patties don't hold up. Through trial and error and my current obsession with sweet potatoes, the quinoa, kale, and sweet potato patty was born. The longer the patties have to chill, the better they hold up to searing. Alternatively, you could bake them, but they will likely dry out a bit. I served the patties in a lettuce wrap with sliced radish and a lemon yogurt sauce. If you want a vegan alternative, use tahini in place of yogurt for a nuttier diary-free sauce.
