Add the lettuce to a clean cutting board with slices of prosciutto cotto, mortadella, provolone cheese, and pepperoncini (if using).
With a big sharp knife, chop everything as small as possible. Note: You can transfer this chopped mixture into a bowl and add the dressing or simply add it on top.
Once finely chopped, add the mayo, Italian seasoning and the pickled juice from the pepperoncini jar.
Mix well and add to your favorite bun. I love the brioche hot dog buns but you can use any you like. Enjoy!
