Blend coriander leaves, mint leaves, green chilies, and ginger-garlic paste into a smooth paste.
In a large bowl, combine the green paste with yogurt and salt.
Add the chicken cubes and coat them evenly with the marinade.
Cover and refrigerate for at least 2–4 hours, or overnight for the best flavor.
Thread the marinated chicken onto soaked wooden skewers or metal skewers.
Preheat the oven or grill to 200°C (390°F).
Grill the kababs for 15–20 minutes, turning occasionally and brushing with butter or oil until the chicken is fully cooked and slightly charred.
Serve hot with mint chutney, onion rings, and fresh lemon wedges.
