Preheat grill to 375 degrees. Put cut chicken pieces in a bowl and the cut veggies and fruit into another bowl. Fill each bowl with half the bottle of spicy peanut vinaigrette. Let marinate for at least 20 minutes, though preferably overnight. Soak skewers in water while ingredients are marinating.
When ready, assemble ingredients on skewer in the following order: green pepper, onion chunk, pineapple slice, chicken piece, orange slice (skew through the skin), pineapple slice, chicken piece. Repeat until skewer is filled (not too tightly). To keep the skewers from sticking, spray the top of the grill with canola oil. Grill for 12-15 minutes (turning skewer at 6 min). Chicken is done once it reaches an internal temperature of 165 degrees.
