1Carefully peel paperlike skin from around each bulb of garlic, leaving just enough to hold garlic cloves together.
2Place each garlic bulb on 12-inch square of heavy-duty aluminum foil. Brush bulbs with oil. Wrap foil securely around each bulb.
3Heat coals or gas grill. Cover and grill 4 inches from medium coals 25 to 35 minutes or until garlic is tender when pierced with toothpick or fork.
4Grill bread 4 inches from medium coals about 5 minutes, turning once, until golden brown. To serve, gently squeeze garlic out of cloves; spread on bread.
