Sort of! The filling is different, but the general idea is the same.
By the way, there's a small Italian restaurant not far from our house that makes an incredible calzone... yummmmm...
I have a calzone press that I've never used. Joseph keeps bugging me to make some. Maybe tomorrow... He may not have school because they're expecting another 3-5" of snow, and it doesn't start falling until about 5am, so that means it will be nice and slushy just about rush hour. Delightful.
