Begin by bringing a large pot of salted water to a rolling boil over high heat. Add the fusilli or rotini pasta and cook for about 9-11 minutes or until slightly past al dente. Once cooked, drain the pasta in a colander and immediately toss it with a drizzle of extra-virgin olive oil to prevent sticking. Allow the pasta to cool to room temperature before proceeding.

In a spacious mixing bowl, combine the cooled pasta with halved cherry tomatoes, mini mozzarella balls, diced red bell pepper, sliced English cucumber, chopped red onion, Kalamata olives, and pepperoncini. Use a spatula or spoon to gently toss the ingredients together until evenly mixed.

Pour your desired amount of Italian dressing over the pasta and vegetable mixture. Add a pinch of sea salt and a few twists of freshly ground black pepper to taste. Toss everything thoroughly to ensure an even coating of dressing on all ingredients.

Before serving, stir in the chopped fresh parsley and gently mix to distribute the herb's freshness throughout the salad. Adjust the seasoning if necessary, adding more salt or pepper for balance. For the final touch, add fresh basil leaves just before serving.
