It consists of layers of bread, ham, linguiça (Portuguese sausage), and steak, all topped with melted cheese and a rich tomato and beer sauce. The sandwich is then typically served with a fried egg on top and accompanied by french fries. The combination of flavors and textures in Francesinha makes it a truly indulgent and satisfying meal. It is often considered a comfort food in Portugal and is enjoyed by locals and tourists alike.
