Mold the Cheese: Preheat oven to 350°. Add two pearl-sized cheese balls into each silicone ghostface mold and heat for about 8 minutes to soften the cheese. Remove from oven and use the back of a spoon to smash the softened mozzarella ball and work it into the mold. Excess liquid will be released from the fresh mozzarella and will be hot, so take care not to burn yourself while you work the cheese into the mold. Transfer the mold into the refrigerator and allow to chill for 10 minutes before removing them from the mold. Place molded cheese in a plastic container and repeat with remaining pearls of cheese. Refrigerate until ready to use.
Boil pasta according to package directions. Drain and rinse with cold water until pasta is cooled. Transfer pasta to a large bowl and add pepperoni, red bell peppers, zucchini, shallots, dried Italian seasoning and salt and pepper. In a medium bowl, mix Italian dressing, prepared Pesto and garlic and add about half of the dressing to the pasta. Refrigerate for at least an hour or overnight to allow the flavors to meld. When ready to serve, add the cheese Ghostfaces and top with the remaining vinaigrette. Adjust seasonings to taste. Add fresh basil and parsley to garnish.
