Our local pizza shop sells a "doagie" which is pizza crust on the bottom (round, whole pie, baked), then layers on all hoagie ingredients (meat, cheese, lettuce, mayo, tomato, etc), then puts another pizza shell (already baked) on top. It's cut into triangles like a traditional pizza. So basically, a hoagie but with pizza crust, in the size & shape as a whole pizza. It's pretty cool.
