I was in New London, NH yesterday on the way down the interstate 30 miles north of Concord and was at a place called Pizza Chef - or something like that - and had a "Syrian" which was basically a pita cut in half (destroying the pocket effect) with stuff between inside and baked. This was incredibly good. What happened was the cheese glommed into the veggie contents and the pita halves got a crisp consistency - all fed into my gaping maw for about 5 bucks and toasty warm. No messy tomato sauce or anything.

I have no idea if the Syrian was just this one shop's specialty or whether it is a broader New Hampshire thing.
