I have been working on this most of the summer. I am using a balsamic vinaigrette called Cheltam House. Most definitely a sweeter vinaigrette than most! I have never liked "dry" pasta salad--I prefer most pasta salads mayo-based, but I love this salad dressing and wanted to try it on something other than a lettuce salad. I also prefer more veggies than pasta, so adjust the pasta to your style. I also hate soggy cheese and tomatoes in any salad, so I only make enough to eat in one sitting.
