In a large mixing bowl, combine ground chicken, finely chopped onion, minced garlic, and chopped parsley. Add ground cumin, coriander, salt, and black pepper; mix thoroughly.

Wet your hands slightly and shape into 10-12 compact oval koftas.

Preheat your grill to medium-high heat. Lightly oil the grates with a paper towel dipped in olive oil.

Grill the kofta for 5-7 minutes per side until golden brown and cooked through, with an internal temperature of 75°C (165°F).

In a separate bowl, mix plain yogurt with lemon juice and a pinch of salt until smooth.

Serve hot kofta with the garlic yogurt sauce and garnish with parsley or lemon slices.
