Place ribs in shallow pan; season with salt and pepper. Keep refrigerated until ready to grill.

Prepare grill for indirect cooking. While coals are heating, prepare barbecue sauce.

Heat oil in large nonstick saucepan over medium heat. Add onion and garlic. Cook and stir 5 minutes or until onion is tender. Stir in remaining ingredients. Reduce heat to medium-low, cook 15 minutes, stirring occasionally.

Add ribs generously with sauce. Arrange ribs on grill over drip pan. Cover and grill 45 minutes to 1 hour or until ribs are tender and browned, turning occasionally. Brush ribs with remaining sauce.
