To make dough, combine flours and add yoghurt. Mix with wooden spoon.
Knead on a floured board until dough is no longer sticky (approximately two to three minutes). Add more flour if necessary.
Cut into 6 portions and roll each portion into a ball. Cover with damp tea-towel or plastic cling film and refrigerate for 10 minutes.
To make filling, wash spinach. In a frying pan, heat spinach and 1 tablespoon of water. Cook for 2 minutes or until spinach has wilted. Set aside to cool (if using frozen, defrost in microwave).
Grate cheese and dice feta.
Give each portion of dough a quick kneed on a floured board. Roll each dough ball into a thin circle using a floured rolling pin.
Top half of dough with some spinach, grated cheese and feta. Make sure to leave some space around the edge. Fold in half to enclose filling, trim edges (if necessary) and press edges with a fork to seal.
Using a pastry brush, brush one side of the gozleme with oil.
