Slice the mozzarella so as to get roughly square pieces that will fit on the bread

Tips
If you like you could replace the anchovy with cooked ham
Trivia
The fried mozzarella sandwich is a classic of Neapolitan cookery, but is also traditionally made in other regions such as Venice, where instead of the classic breadcrumb coating a batter is used! The result is puffy and fluffy!
