I worked at pizza place here in Rochester. Even though Calzones were not on the menu. If certain customers called we would make them Calzones. Both of them were just medium pizzas folded in half. Same sauce and ingredients as their Pizza. Around Easter time we would put boiled eggs and chopped Mortadella instead of Pepperoni. No cheese just sauce. Egg wash and no cuts. For some reason the weirdo customers liked them when they exploded.
