Start with a base layer of shredded lettuce, then add your meats, cheese, tomatoes, banana peppers and red onions in a pile.
Chop up everything together, making sure it’s well mixed together.
Next add mayonnaise, olive oil, red wine vinegar, salt, pepper, and Italian seasoning.
Chop one more time to incorporate.
Scoop a pile of the chopped Italian ingredients onto a hoagie roll and serve.
