How to make
Dissolve the yeast in warm water with a little sugar, until it is activated. Together with the flour, yeast, yoghurt, oil, remaining sugar and salt, knead an elastic dough. Allow to rise covered with a towel for about 40 minutes. Then knead it and shape it into 12 equal balls.
Each ball is rolled out thinly on a surface coated with oil. Put a little crumbled feta cheese in the middle, and optionally add the grated cheese. Fold and roll them again with the filling until they thin out.
Bake all of them in a hot, dry, non-stick frying pan. The finished pitas with feta cheese are topped immediately with a little butter.
