Back in the day our neighborhood pool sold "ultimate pretzels". They were a sandwich made up of ham and cheese with some mustard in between a soft pretzel that had been split in half to act as the bread. In Philly, the pretzels are delicious and fresh, most are ladder shaped, or like a skinny 8. I was trying to come up with some ideas of how to re-create this treat for a fantasy football party I'm having soon. One of my first ideas was to substitute the ham for prosciutto and the regular old cheese for some sharp provolone with some spicy mustard. I was curious what other combinations people could come up with. Any thoughts?
