Place the chicken, lemon rind and juice, 5-spice powder and soy sauce in a bowl. Stir to combine, cover, then leave to marinate in the refrigerator for at least 1 hour or overnight.
Thread the chicken pieces on to 4 presoaked wooden skewers, pushing them tightly together. Grill for 10 minutes under a preheated moderate grill. Turn the skewers, baste with any remaining marinade, and grill for a further 10 minutes. Serve on a bed of vegetables, if liked.
