Cook spaghetti according to package directions, then rinse in cold water and drain. Set aside and let cool.
Place tomatoes, zucchini, squash, peppers, onion, cucumber, olives, and cheese in a large bowl.
Add cooled spaghetti noodles and mix well.
In a small bowl, mix together the salad dressing, Parmesan cheese, paprika, and garlic powder.
Pour on top of the spaghetti and vegetables and mix until combined.
Sprinkle the top with Salad Supreme.
Let sit in the fridge for at least 2 hours before serving (this salad gets better with time, as the flavors meld together).
Notes
You can make this pasta salad up a day ahead of time if you need to and it will turn out perfectly fine, not to mention it allows those flavors to develop even more!
