In a spacious mixing bowl, combine the cooled pasta with cherry tomatoes, sliced black olives, diced roasted red peppers, toasted pine nuts, and freshly chopped basil leaves. Next, add some Parmesan cheese, which will melt slightly into the warm pasta, imparting a creamy texture. Drizzle over the pesto sauce, ensuring to coat every ingredient. Season with a pinch of salt and freshly ground pepper for the best taste.
