Cook pasta according to package directions until soft, (do not cook el dente) Rinse well with cold water and shake out excess water.
Combine all other ingredients, adding cheese last. Add 1 bottle of dressing, and mix well. I put down 2 bottles in the ingredients section, because I always add more then 1 bottle. Chill. Prior to serving stir salad well, to mix dressing at the bottom of the bowl.
