In a small bowl, whisk together mayonnaise, Italian dressing, and Italian seasoning. Set aside.

In a large bowl, add shredded chicken, salami, pepperoni, provolone cheese, cherry tomatoes, banana peppers, and red onion.

Add the dressing to the chicken mixture and toss well to combine. Refrigerate for about an hour before serving. Note: Add some of the dressing, taste, then add more if needed.

Serve on croissants, bread, or rolls for sandwiches.
