Place chicken in a steamer basket over a saucepan half filled with boiling water along with cinnamon and star anise and steam for 6-8 minutes or until cooked to your liking.
Combine coriander, chilli, lime zest and juice, soy sauce, sugar, wine, spring onion, galangal and garlic in a bowl. Pour over hot coconut oil and whisk to combine.
To serve, cut chicken into thick slices, arrange on a serving plate with 3-4 tablespoons of sauce drizzled over and garnish with remaining coriander.
