In a small bowl, whisk together all of the ingredients for the dressing. Set aside while you prepare your subs. This will give the flavors time to combine.
Slice the sub rolls in half and hollow out the insides. (If you are concerned about wasting the fluffy bread innards, you can save them and use them to make whole grain breadcrumbs later, okay?)
Drizzle both halves of each sub with your Italian dressing.
You can add the sandwich fillings however you like, but my way is obviously the best:
Place the turkey in one half of each sub roll and top with one slice of provolone that has been cut in half. Arrange pickles and chopped banana peppers/pepperoncini in an even layer on top of the provolone. Fill the other half of each sub roll with lettuce. Top with tomato, red onion, and sliced bell peppers.
Carefully sandwich the two halves of each sub together. Slice and serve. Enjoy crushing your slimming sub, dudes.
