Guys in some of the TAs in Glasgow you can order a thing called a hoagy or some similar name. They take a freshly cooked nan pile on top Shish Kabab, wait for it Donar kebab and in some places for a wee drop more pennies vegetable pakora and top with sauce and then they roll it up and serve it in a paper wrap.
The nans in Glasgow are huge compared to many I have found elsewhere in my travels and so this big all in one meal is something to see and taste. By the time the remnants of the nan is soaked in all the sauce and fatty residue it is probably a killer but tastes amazing. PP
