Cut the chicken meat into small cubes.
Blend the marinade ingredients in a food processor. Add in a little water if needed.
Marinate the chicken pieces for 6 hours, or best overnight.
Thread a few pieces of the chicken meat onto the bamboo skewers.
Grill for about 2-3 minutes on each side until nicely charred. Baste and brush with some oil while grilling.
Serve hot with the fresh cucumber pieces and onions.
