Luckily, your typical Calzone is not nearly as big as that article.
For people like me who like pizza, but dont really know what a Calzone is, let alone an Empanada;
A Calzone resembles a type of Italian Burrito, if one ever existed. This “Italian Burrito” has soft flaky crust as wrapping. The wrap around crust is usually toasted and buttered.
Most every restaurant made it with standard pizza dough but one restaurant about 20 miles away was famous for their calzones and made them with a flakier crust than the others. They were my favorite. It was Vecchio's cafe in Polcenigo.
