Heat 1 tablespoon of olive oil in a skillet over medium heat. Add diced onion and sauté for about 5 minutes until translucent. Stir in minced garlic and cook for 30 more seconds before removing from heat.

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

Shape the mixture into eight uniform patties, each about half an inch thick. Place on a plate or tray.

In the same skillet, heat remaining olive oil. Add the patties and sauté for 5-6 minutes on each side until golden brown and cooked through.

Transfer the patties to a paper towel-lined plate to drain excess oil. Serve warm with fresh veggies or tzatziki sauce.
