In a bowl, combine 1/2 cup sweet-and-sour sauce, pineapple juice, teriyaki sauce and garlic. Pour half of marinade into a large resealable plastic bag; add chicken.

On metal or soaked bamboo skewers, alternate meat with onions, peppers and pineapple. Brush kabobs with reserved marinade. Sprinkle with crushed red pepper flakes. Grill, uncovered, over medium heat for 4-5 minutes on each side. Baste with marinade. Continue turning and basting for 10-12 minutes longer or until chicken is no longer pink Serve with rice. Serve remaining sweet-and-sour sauce on the side.
