This is just me parking a link for a thread on upstate NY diners. Some pretty fierce debate on the Dino BBQ but I am liking the sound of Johnny's Hot Truck and its grilled pizza on bread.

On West campus there was Johnny’s hot truck. Johnny’s only (or at least used to) sells french bread pizzas. Learning the acronyms for the many varieties of pizzas was a rite of passage in every student’s four year drinking career. Yes, the rumor is that Stouffers licensed the concept many years ago from Johnny to sell in supermarkets. Johnny has retired after 35+ years and sold the business so it will be interesting to see if the quality is still the same. During reunions, Cornell allows Johnny’s hot truck to drive up on campus and park in the middle of the Arts quad, right next to the beer tents. It really is a beautiful arrangement. Nothing like drunken alumni reliving their college years by inhaling pippin hot french bread pizzas

Sounds like a Polish zapjakanky...or however you spell it. In Poland there would be these plastic cube shops on the curb by the roadside, dubbed zap shacks. Through a tiny window you could order a half a french bread sliced long-ways with a thin layer of tomato sauce, wild mushrooms and blandish generic cheese. Once, in Szczecin, there was leek as well under the cheese. The whole thing is grilled under the salamander/broiler and for 35 cents worth of basically worthless Polish zloyty, fast food heaven.
