2In a large bowl, mix mayonnaise, soy sauce and seasonings. Add the rest of the ingredients and mix well. Refrigerate at least 1 hour before serving. Remove from refrigerator 15 min. before serving to take the chill off.
Note: I actually make the dressing a day ahead in a small bowl as well as cook the chicken. When I assemble the salad I save some of the dressing in case I need to add a touch more just prior to serving. Sometimes the pasta will soak up some of the dressing while it sits in the refrigerator.
