Cook the noodles according to package instructions, then strain it and rinse with cold water to quickly cool them down.
Chop all vegetables (zucchini, cherry tomatoes, green and red peppers, red onions, cucumbers, and black olives) and place them in a large mixing bowl.
To make the sauce, whisk in Italian dressing, sesame seeds, grated parmesan cheese, paprika, celery seeds, and garlic powder in a separate mixing bowl.
To finish, toss the cooked pasta with all the chopped vegetables, then pour the marinade over it and mix well.
Cover the pasta in plastic wrap and chill it in the refrigerator for at least 3 hours before serving.
