Blend together dressing and cream cheese. Among the tortillas, evenly layer half the turkey, cheese, dressing mixture, avocados, tomatoes and lettuce, leaving a 1-inch border around edges. Repeat layering with remaining ingredients. Fold the right and left edges of tortillas into centers over the filling. Fold the bottom edge toward the center and roll firmly until completely wrapped. Place seam side down and cut in half diagonally.
