In a large bowl, add the cooled pasta, red onion, broccoli, green olives, cheese, banana peppers, pepperoni, salami, cherry tomatoes, and green pepper. Set aside.
In a small bowl, whisk together the red wine vinegar, sugar, dried parsley, Italian seasoning, garlic, and extra virgin olive oil. Add salt and pepper to taste. (About 1 teaspoon salt and 1/2 teaspoon pepper.)
Add the dressing to the bowl of pasta. Toss to combine. Cover with plastic wrap and chill in the refrigerator for at least two hours. Toss again before serving.
