In a large bowl, combine the cooked pasta, salami, mozzarella cheese, roasted vegetables, black olives, red onions, and basil.
Drizzle the balsamic dressing over the salad and toss gently to coat.
Season with salt and pepper to taste.
Refrigerate the pasta salad for at least 30 minutes to allow the flavors to meld together.
Serve chilled and savor the Italian-inspired antipasto flavors!
