PLACE ribs in large saucepan or Dutch oven. Add enough cold water to completely cover ribs; cover pan with lid. Bring to boil on medium-high heat. Reduce heat to medium-low; simmer 20 min. Drain.
PREHEAT grill to medium heat. Grill ribs 10 min. or until cooked through (160°F), turning occasionally and brushing generously with the barbecue sauce mixture.
