Prepare the dough and let it rest for approximately 1 hour. Beat the olive oil and 1/2 glass of water and combine them all with the yeast. Mix well and add the milk and eggs. Continue kneading by gradually pouring the remainder of the flour and the rest of the ingredients for the dough. Knead the dough well and leave it aside. Mix well all ingredients for the filling. Then roll out a pastry sheet and cut circles in the size of a saucer. Place a tablespoonful of mizithra cheese on each circle and fold into squares.
