Boil a large pot of salted water and cook the tortellini according to package instructions until al dente.
Drain the tortellini and rinse under cold water to stop the cooking process and cool completely.
In a large mixing bowl, combine the cooled tortellini, salami, mozzarella pearls, cherry tomatoes, cucumber, red onion, olives, and pepperoncini.
Pour the Italian vinaigrette over the salad components and toss gently to ensure all ingredients are evenly coated.
Season with salt and black pepper to taste and garnish with fresh parsley.
Refrigerate for at least 30 minutes before serving to allow flavors to meld.
