Cook and drain pasta. Place bacon, tomatoes, green onions, and pasta in large mixing bowl. In another bowl combine dressing, onion, egg, Worcestershire, and hot sauce. Pour over pasta and combine. Refrigerate at least 1 hour.

Remove from refrigerator 30 minutes prior to serving. If salad appears dry, add a small amount of olive oil. To serve, arrange leaf lettuce on a platter spooning salad onto center.
