Fuqi Feipian (夫妻肺片, literally Married Couple's Slices of Lung) is a popular Szechuan dish - often served cold - which is made of thinly-sliced beef, beef lung/stomach/tongue (the latter two are more common in the US), and a generous amount of spices, including Szechuan pepper. True to its roots, the desired taste should be both spicy and mouth-numbing.
