Cook the rotini pasta in salted water according to package instructions, usually 8-10 minutes. Drain and rinse under cold water.

Combine cooled pasta with chopped pepperoni, salami, and ham in a large bowl. Toss gently to mix.

Fold in shredded lettuce, sliced onions, banana peppers, black olives, and tomatoes. Combine gently.

In a small bowl, whisk together mayonnaise, vinegar, olive oil, Italian seasoning, salt, and pepper until smooth.

Pour the dressing over the pasta mixture and toss thoroughly to coat evenly.

Cover and chill in the refrigerator for at least 30 minutes.

Stir before serving. Optionally garnish with extra parmesan or herbs.
