In a large mixing bowl, combine the ground chicken, feta cheese, breadcrumbs, egg, garlic, parsley, dill, lemon zest, oregano, cumin, salt, and pepper. Mix gently until just combined.
Using your hands or a small scoop, form the mixture into 1-inch meatballs (about 16-18 meatballs).
Choose your cooking method: Pan-Fried - Heat 1-2 tablespoons of olive oil in a large skillet over medium heat. Cook the meatballs in batches for 6-8 minutes, turning occasionally, until browned on all sides and fully cooked (internal temperature of 165°F/75°C). Baked - Preheat the oven to 400°F (200°C). Place the meatballs on a parchment-lined baking sheet and bake for 18-20 minutes, flipping halfway through.
Serve the Greek Chicken Meatballs warm with tzatziki sauce on the side for dipping. Pair with pita bread, a fresh salad, and lemon wedges for a complete Mediterranean meal.
