This recipe has been an ever-changing work in progress. If you don't have a slow cooker (or prefer not to use one) bake in a 250 degree oven. It is a recipe very forgiving of amounts and ingredient changes. Optional changes -Add more of the mild pepperoncini slices, or even add some of the juice. Top with shredded mozzarella, or provolone, cheese. Or, top with caramelized onions, green peppers, and mushrooms, if desired. You may want to serve the broth in small bowls, for dipping.
