Boil a large pot of salted water over high heat. Add rotini pasta and cook until al dente, about 8-10 minutes. Drain and rinse under cold water to cool.

In a large mixing bowl, add the cooled rotini pasta. Layer in diced pepperoni, salami, and ham, tossing gently to combine.

Fold in shredded lettuce, red onions, banana peppers, black olives, and diced tomatoes, mixing gently but thoroughly.

In a separate bowl, whisk together mayonnaise, red wine vinegar, olive oil, Italian seasoning, salt, and black pepper until smooth.

Pour dressing over the pasta mixture and toss until everything is coated evenly.

Cover and chill in the refrigerator for at least 30 minutes to allow flavors to meld.

Stir before serving. Garnish with extra grated parmesan or fresh herbs if desired. Serve chilled.
