In a large mixing bowl, combine the ground chicken, finely chopped onion, minced garlic, chopped fresh parsley, ground cumin, ground coriander, salt, and black pepper. Mix thoroughly for about 3-5 minutes.

Wet your hands and shape the mixture into small oval koftas, about the size of a golf ball, packing them tightly.

Preheat your grill to medium-high heat (about 375°F or 190°C) and brush with olive oil to prevent sticking. Heat for about 5-7 minutes.

Place the koftas on the hot grill and cook for 10-12 minutes, turning occasionally until golden brown and cooked through.

In a small bowl, whisk together the plain yogurt, lemon juice, and a pinch of salt until smooth.

Serve the grilled koftas warm on a platter alongside the garlic yogurt sauce for dipping.
