Sauté the diced onion in one tablespoon of olive oil over medium heat until translucent, about five minutes. Add minced garlic and cook for another thirty seconds.

In a large bowl, combine sautéed onion and garlic with chopped spinach, ground chicken, breadcrumbs, Greek yogurt, fresh dill, lemon juice, oregano, paprika, cumin, salt, and pepper. Mix until well combined.

Shape the mixture into approximately eight patties about half an inch thick.

Heat the remaining two tablespoons of olive oil in a skillet over medium heat. Cook the patties for about five to six minutes on each side until golden brown and cooked through.

Drain the patties on paper towels to remove excess oil before serving.
