The Italian panini culture is a great thing. In many bakeries and allimentari you can choose a panini and have it filled with all sorts of delicacies.
Obligatory olive oil is dripped onto the bun and salt is sprinkled on it. Then, depending on your choice, prosciutto crudo or cotto, salami or cheese is served on top together with mushrooms, anchovies, fresh or dried tomatoes or olives - everything that is in stock at the counter.
Sometimes the deliciously filled panini goes into the oven for a moment and then nothing stands in the way of enjoyable consumption.
