Heat 1 tablespoon of olive oil in a skillet over medium heat. Add diced onion and sauté for about 5 minutes until the onion becomes translucent and fragrant. Then, stir in minced garlic and cook for an additional 30 seconds.

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

Shape the combined mixture into approximately eight patties, each about ½-inch thick.

In the same skillet, add the remaining tablespoon of olive oil and heat over medium. Place the patties in the skillet and cook for 5-6 minutes on each side, or until golden brown and cooked through.

Once cooked, transfer the patties to a plate lined with paper towels to drain excess oil. Serve warm.
