In a shallow glass dish, mix the soy sauce, brown sugar, sherry, sesame oil, ginger and garlic. Stir the chicken pieces and pineapple into the marinade until well coated. Cover, and marinate in the refrigerator at least 2 hours.
Preheat barbecue to medium-high.
Thread chicken and pineapple alternately onto skewers.
Cook on the barbecue 15 to 20 minutes, turning occasionally, or until chicken juices run clear.
The pineapples have been so good lately i've been looking for more ways to use them and chicken and pineapple go together better than I thought:-) Next time I would halve the sugar, cos the pineapples are sweet enough! - 07 Feb 2009
