Francesinha is a popular Portuguese sandwich that originated in Porto. It is made with 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 grilled until the cheese is melted and bubbly. Francesinha is often served with a side of fries and a fried egg on top. It is a hearty and indulgent dish that is perfect for meat lovers.
