Preheat a charcoal barbecue, grill plate or grill pan until hot.
Thread the marinated chicken onto 8 metal or soaked bamboo skewers.
Lightly oil the grill, then cook the skewers for 7–8 minutes, turning often, until lightly charred and almost cooked through.
Begin basting with the reserved marinade and cook for a further 2–3 minutes, turning often, until glossy and cooked through.
Rest the skewers for 5 minutes, then serve with coriander sprigs, sliced cucumber, red onion and chilli.
