This pasta salad is so easy and can be made with store-bought Italian salad dressing and any of your favorite vegetables. We usually use Wishbone Italian or Kraft Zesty Italian for the dressing. It can be made with any egg free noodles (we use DeCecco or Garafalo). I also like to make it with whole grain noodles so it is more filling. The best tasting whole grain Rotini I've found is Trader Joe's Quinoa and Brown Rice Rotini, which also happens to be gluten free. It tastes very similar traditional pasta compared to other whole grain options. This recipe is so flexible, you can substitute any vegetables or add or take away vegetables depending on your preference. Whatever goes into this pasta salad depends on what is in my refrigerator at the moment. Sometimes we serve cubes of cheddar or mozzarella cheese on the side so our dairy-eaters can add it to their salads. The amount of salad dressing can also be adjusted. If you prefer it more mild, use closer to 1 cup dressing, but if you prefer a stronger taste, add 1 1/2 cups, or more if desired. This pasta salad tastes best if it sits in the refrigerator for a couple of hours.
