1.  Preheat the broiler to high. Soak 4 bamboo skewers in hot water. Pour the sauce into a shallow dish and add the chicken fillets, turning to coat them in the sauce.

2.  Thread on to the skewers and cook under the broiler for 4 minutes on each side until cooked through and well browned.

3.  Warm the Nan breads under the broiler, then split in half. Remove the chicken fillets from the skewers and push them into the Nan breads. Squeeze over a little lime juice and enjoy.
