How to make
Mix the yoghurt with the baking soda, add the melted butter and crumbled feta cheese.
Add the sifted flour and stir well until you get a thick dough.
Pour the dough into a prepared buttered tray. Put it to bake in a preheated moderate oven.
Take out the phyllo pastry from the oven and while still warm, sprinkle it with powdered sugar.
