Preheat oven to 350°F degrees. Lightly spray 9x13 baking dish with cooking spray.

In a food processor, place the peeled and quartered fresh zucchini. Pulse for 10-15 seconds or until zucchini has been shredded/diced to small pieces.

Boil the pasta as directed on the package. Once pasta is soft, drain the water and add the pasta to the 9x13 baking dish.

Pour the pizza sauce on top of the pasta. Add the grated zucchini, add pepperonis (reserving 12-16 slices), and mozzarella cheese. Stir together until noodles are well coated with sauce and cheese is evenly spread out. Place the remaining reserved pepperonis on top of the pasta bake.

Bake for 15-20 minutes or until cheese has melted and the pepperonis on top are crisp on edges.

Remove from oven and serve.
