What in the world is a byrek? I had to consult my good friend Google on this matter. I learned it was a phyllo dough wrapped pocket of cheeses, veggies, and/or meats and baked until golden and served warm. These delicious pouches of yumminess hail from Eastern European countries like Turkey, Albania, and Croatia. They are made in all different shapes and sizes. The Authentik Byrek truck serves them in a large pie-shaped wedge.
