Why the hell do they call a loaf of meat NAIL (PREGO)?? A little popular culture to explain this to us.

The “Prego no Pão” or, in a literal translation, “Nail in the Bread”!

Who would have thought that the nail, or steak on bread, appears in Portugal at Praia das Maçãs?

“The real story is related to the name Manuel Dias Prego, one of the first inhabitants of Praia das Maçãs in the late 19th century, where he owned a tavern, Taberna do Prego. In this tavern Manuel Prego served fried veal slices or baked in tasty bread and accompanied by wine from the region.
The meat on bread quickly became a success in Praia das Maçãs and surroundings. It is said that it was in this place that José Malhoa painted his famous painting “Praia das Maçãs”. Who knows if savoring such a delicacy while painting!
Over the years, the name of the sandwich came to be commonly known as Prego, in honor of its creator, and in the beginning of the 20th century the recipe had already been copied to other places, and Prego started to be part of the menus of taverns across the country and not just in Sintra.”
