Pie and mash

Pie and mash is a traditional dish consisting of a pie filled with either chunks of beef or ground beef, and a side of mashed potatoes. Although the pies are nowadays filled with ground beef, in the past they were filled with eels from the Thames, which is the reason behind numerous Pie, Mash, and Eel shops in London. Inexpensive, yet filling, pie and mash is still a staple dish of London's working class.
