This pumpernickel, pastrami, onion and apple sandwich is based on a recipe by Emily Hobbs ( a constestant on Food Network's Ultimate Recipe Showdown). I've made a couple changes based on personal preferences and such. This can be served with an au jus broth made from beef broth, garlic, and a splash (or more) of ale. I like it with cabbage soup. But, this sandwich is great on its own as well. Enjoy!
