Trim the ends off of the zucchini. Use a vegetable spiralizer to create wide, ribbon-shaped noodles. (I use Blade "A" on the Inspiralizer.) Roughly chop the ribbons into bite-sized pieces.
In the bottom of a large mixing bowl, combine the Italian Dressing ingredients.
Add all of the ingredients (chopped chicken, vegetables, basil, and sun dried tomatoes) to the bowl, and toss to combine.
Serve chilled. Feel free to make this up to one day ahead, and store it in the refrigerator until you're ready to enjoy!
