It depends on the country you're in. Here in Switzerland we also call it Kebab. We call it Dürüm or Döner Kebab depending on the bread/pita you use(same in Germany).
I thought it was composite meat.
Sometimes you may find it in a grossary stores, maybe you should try gyros meat aswell, it's this similar greek stuff.
Cocktail sauce taste awesome too!
