After opening the packet of phyllo, quarter the pastry so that each phyllo sheet produces four smaller pieces. Set them aside. In a bowl, combine the ingredients for the filling, stir with a whisk to a smooth mixture. Picking up each piece of phyllo, crumple it up in a ball using your hands, just as if you were crumpling a piece of paper, then dip (submerge) each phyllo piece into the yoghurt mixture.
