Preheat barbecue on MEDIUM for 10 minutes. Meanwhile, prepare asparagus by rinsing thoroughly in cold water to remove sand. Snap off the woody ends. Toss lightly in olive oil, place on grill and cook for 8 minutes, turning once. Remove from grill and sprinkle lightly with salt.
Meanwhile, cut each piece of prosciutto in half, lengthwise. Wrap bottom half of each spear of asparagus in prosciutto. Arrange on platter and sprinkle with balsamic vinegar and freshly cracked black pepper.
