Bring a large pot of salted water to a boil. Add the pasta and cook until tender, checking the package for the recommended cook time. Drain and rinse well under cold water.

While the pasta cooks, prepare the basil pesto. In a food processor, combine the fresh basil, pine nuts, parmesan cheese, olive oil, garlic, lemon juice, salt, and pepper. Process until smooth and creamy. Scoop out of the food processor and set aside.

In a large bowl, combine noodles, pesto, cherry tomatoes, mozzarella, pepperoncini, and parsley. Toss until well combined. Taste and adjust seasoning if needed.
