I have a buddy who used to deliver pizzas. So of course he has a million stories of the weird stuff people like to eat. The one that always stuck out the most for me was the woman who wanted a steak and cheese calzone with mayonnaise and lettuce. Lettuce. In a calzone. Mayo I can see (if you've never had a steak and cheese with mayo, try it. Seriously.), but lettuce? It would get all soggy and put out a ton of liquid making everything else soggy too, I would think. Plus cooked lettuce (inevitably iceberg, from a pizza shop) is just nasty, in my opinion.
I think my personal favorite calzone is chicken and broccoli. Like this one. I like it best with a good white sauce, but there are other good ways to do it. The one above was made with braised chicken and I took some of the braising liquid and thickened it into a gravy. Nice and easy, didn't have to make any additional stuff.
How about you guys, do you eat calzones? What do you like in them? Or what would you want to try in them but haven't yet or aren't brave enough? Next time I get some lamb I think I'm going to make a spicy Greek one. With that cheese they set on fire in Greek restaurants that I can't remember the name of. Good times.
I also recently made some dessert calzones that didn't quite turn out how I wanted, but I'll still post about them later this week. If nothing else they taught me a few things. Heh.
EDIT: After reading some of your comments I think I have been vague about the calzone pictured above. There is cheese in there. A heroic amount of mozzarella, even. High quality, Italian deli mozzarella at that. Just so there isn't any misunderstanding. Heh.
