1) Preheat the broiler.
2) In the bowl of a food processor, place chicken, coconut, chopped coriander, egg, sugar, zest, soy sauce, salt, pepper, and spice paste. Process until well combined and divide into 8 equal portions.
3) Moisten hands with water and shape chicken mixture around top half of 8 wooden skewers that have been soaked in water for 30 minutes. Place skewers on a foil-lined lightly greased broiler pan and broil about 12 minutes, turning occasionally.
4) Arrange skewers on a serving dish and garnish with lime slices, cilantro, and red chiles. Serve hot with Wasabi Mayonnaise for dipping.

Heat oil in a medium skillet over medium heat. Add chilli mixture and cook about 2 minutes, stirring. Cool before using.
