I’ve tried googling this, but since I’m not even sure how to spell it, I had no luck.
When I was younger, say early 80’s, when the Puyallup fair was happening, my parents used to buy these super-greasy meat filled pastry things from a vendor outside the fairgrounds. The name I remember is something like flashkikala (I know that’s not right, but that’s what it sounded like to my 6 year old ears.)
They were thin strips of meat, beef I assume, and onions either grilled or deep fried in this thin dough, kinda like a tortilla, but much thinner, maybe filo? They came wrapped in white butcher paper, and the grease would soak right through the wrapper and bag.
<<Wait a sec - are you saying the Puyallup Fair isn’t happening any more? >>
No, I mean at the time of year when the fair was in session, or however the heck one would say such a thing. (does a fair happen, what’s the proper grammar?)
Anyway, no not peroshkis or Kreatopita, similiar but different. Much simpler recipe. I want to say they’re greek… could be lamb instead of beef… I just remember them being very tasty and a special treat.
Given the OP’s constraints (which include very thin dough like filo dough, which discounts stuff like souvlaki or gyros), the only thing I could think of that sounds like that might be the Yugoslavian burek. There are a zillion regional variations, and I’m sure there’s an equivalent in Greece and Turkey, perhaps with a name that sounds more like what you remember.
