The famous francesinha sandwich from Porto. There’s a saying that to be a good resident of Porto, you must eat two francesinhas a day. Francesinha, or Little Frenchie, is a crazy meat-heavy sandwich made with bread, wet-cured ham, linguiça (Portuguese smoke cured sausage), fresh sausage like chipolata, steak, and then covered with melted cheese, topped with a fried egg surrounded by a thick tomato and beer sauce. Daniel da Silva invented the sandwich after having lived in France and Belgium. When he returned to Porto, da Silva adapted the croque-monsieur to the Portuguese taste.
