Start by making the dough: combine the flour and sugar in a bowl. Dissolve the yeast in the water, then add it to the flour along with the olive oil. Begin mixing. Add the salt and knead until you have a smooth, even dough. Cover with plastic wrap and let it rise until doubled in size.

After the first rise, divide the dough and shape it into balls. Keep in mind they will rise again, so size them according to how big you want your calzones. Let the balls rise again until doubled in size.

While the dough balls are rising, prepare the filling by rolling up slices of ham and mortadella with a generous piece of mozzarella inside each.

Trim the edges with a pastry cutter to give them the classic half-moon shape. Once all the calzones are ready, fry them in hot oil for about 1–2 minutes per side, or until golden brown.

Drain on paper towels and enjoy them hot. They're also delicious cold the next day, if you have any left!

Who can resist that melty, cheesy center? We sure can't. Enjoy!
