It's essentially a French dip sandwich that Kraków arrived at on its own, long before the American version had any presence there.
Slices of slow-roasted pork shoulder are stuffed into a soft bread roll and dunked into the rich, dark gravy left behind in the roasting pan — sold at food trucks and Kraków bar mleczny counters as a hearty, drippy handheld lunch.
