In a large mixing bowl, combine the ground chicken, chopped onion, minced garlic, parsley, cumin, coriander, salt, and black pepper until well blended.
Shape the mixture into small, oval-shaped koftas.
Warm up your grill and lightly coat it with olive oil to prevent sticking.
Cook the koftas on the grill for 10 to 12 minutes, turning them occasionally to ensure they are evenly cooked.
While the koftas are grilling, prepare the yogurt sauce by whisking together plain yogurt, lemon juice, and a pinch of salt.
Plate the grilled koftas and serve alongside the garlic yogurt sauce for dipping or drizzling.
