Soak skewers in cold water for 1 hour. This will prevent them burning on the barbecue.
Cut the chicken into 3 cm cubes.
Cut the pineapple slices into 3 cm pieces.
Thread the chicken, pineapple, capsicum and onion onto bamboo skewers.
Preheat a barbecue hot plate to medium-high and spray with cooking oil. Add kebabs and cook for about 8 to 10 minutes, turning occasionally until chicken is cooked.
Combine barbecue sauce with water in a small bowl. Brush over kebabs. Remove from barbecue. Cover with foil to keep warm.
Meanwhile, toss salad leaves, tomatoes and cucumber in a large bowl.
Serve kebabs with rice and salad.
