Cook the spaghetti according to the package directions. Drain and cool under cold water. Continue to drain to ensure the pasta is as dry as possible.
Combine all the prepared vegetables, herbs, and parmesan in a large mixing bowl. Add the drained and dried cooked pasta followed by the dressing. Toss several times to combine. Season to taste.
Notes
Store this salad in an airtight container in the refrigerator for 4 to 5 days; this is one of those salads that tastes even better after the flavors mingle for a day or two in the fridge! I don’t recommend freezing this recipe.
