Roll out the dough with rolling pin and then also stretch it with your hands so it becomes very thin. You can stretch it at once or make a few small ones if you don't have a large space.
Put filling all over the dough.
Roll the dough and put it on the baking pan previously coated with olive oil. You can coat burek with oil so it becomes more crunchy once it's baked.
Bake for about 45 minutes on 200°C. Put a bowl of water at the bottom of the oven for a crunchier burek.
