That is like what we call Burek http://www.coolinarika.com/recept/burek-kao-iz-burekdzijske-pekare-sa-sirom-mesom-i-jabukama/
this one is serbian or bosnian recipe. We have it with few different fillings. I belive you have it as well. Yours is with spinach and feta cheese, We have it with cottage cheese, meat, apples which I think it's strange to eat and last few years Pizza burek, so cheese ham and tomatoes. As soon as you make it as sweet it becomes strudl. Oh and I love your greek yoghurt with honey. To die for.
yep, that's it basically. All balkan countries have similar recipes, it dates back to Ancient Greek and Ottoman empires (this is why Turkish people have it too). Some people do it with phyllo, some others with plain dough, fillings may vary but it still tastes great after all :laugh: :laugh:
