Trim tops of lettuce heads to remove broken or limp ends. Cut lettuces in half lengthwise; mist or lightly brush cut sides of romaine with oil. Grill, cut side down, directly over a grill preheated to medium-high heat until dark grill marks appear (about 2 min.). Place grilled lettuce on a serving plate(s); drizzle with dressing and sprinkle with onion, nuts and noodles. Serve immediately.
