Francesinha

 

There are dishes in Porto that should be tried, and then there are dishes that absolutely must be tried. And the one that falls into the latter category is the Francesinha –– a sandwich unlike just about any other in all of Portugal. This gargantuan local delicacy, just like a Croque Monsieur, is one of the region's best-kept secrets: featuring succulent layers of pork, steak, and ham, topped with tomatoes and melted cheese, then drizzled with beer gravy and sandwiched between two generous slices of bread, the Francesinha is an original Porto creation that eats like a meal, and then some. 

I ordered one but was only able to eat about three quarters of it. Not to be repeated but as a tourist it was a must do. It came with chips.
