For this: I know the reply is probably a bit slow, but many of the posters have the ideas about right, with the cold cuts. I like pepperoni on pizza, but not cold in a sub. That one needs to be hot.
I myself don't like bell peppers, I like pepperoncini.
I think you could put together a nice vinaigrette. With shallots, garlic, olive oil, balsamic vinegar, good salt and pepper, and a little bit of Coleman's dry mustard. Whisk it with vigor. And you could throw just a little cracked red pepper in the dressing, the type they hand out at pizza places in shakers.
Don't be stingy with the provolone.
I don't need tomato in there.
I actually do like something like iceberg, which stands up pretty well to the dressing, I like it sort of sliced finely (like about as narrow as you can, then tossed a little), not all chopped up. Romaine is a bit much, but red tip leaf lettuce is good, if you use the sturdier end. Use the softer end for a salad first if you like. You could throw in some mushroom of some kind, and definitely some chopped or sliced black olive. Maybe even a little green onion.
Good Luck!
