In a medium sized mixing bowl, combine the mayo, red wine vinegar, banana pepper juice, dried oregano, salt and pepper. Whisk together until the mixture's smooth and evenly combined, then set aside.
On a cutting board, cut all the meats, cheese and veggies into tiny chopped pieces. The smaller the better.
To a large mixing bowl, add the chopped lettuce, meats, cheese, tomatoes, onion, and banana peppers. Stir to combine.
Pour the dressing mixture into the bowl with the combined meats and vegetables then toss until evenly combined.
Transfer the dip to a serving dish and serve immediately with your favorite dipping options, and enjoy!
