Cook quinoa as per package instructions. Chop vegetables and crumble the cheese for serving the bowls.
To make quick pickled onions, place sliced red onion in a small bowl, pour boiling water until covered and let stand while preparing other ingredients. Drain before serving.
In a large bowl, add ground turkey, feta cheese, olives, onion powder, garlic powder, salt, pepper and mix well with a spatula. Using wet hands, form 10 small-medium burger patties and place on a large plate.
Preheat large non-stick skillet on medium heat and add 1 tablespoon of oil. Add 5 turkey burgers, cook for 5 minutes or until golden brown, flip and cook for another 4-5 minutes or until thermometer inserted in the center registers 165F. Repeat with remaining batch.
To serve, in each bowl place some cooked quinoa, 2-3 burger patties, cucumbers, tomatoes, olives and tzatziki. Sprinkle with feta cheese and dill. You can add whatever else you like. Enjoy!
