In a bowl, mix all of the ingredients together to form a soft dough.
Cover the dough with cling film, set it aside in a cool place and allow it to rest for about 30-40 minutes.
After the resting time is up, if the oil has risen to the top of the dough, add some more flour to regulate the consistency.
Using a rolling pin, roll out the dough on a floured surface and use a biscuit cutter or cup edge to cut some circles (about 12cm in diameter).
Place a teaspoon of the filling in the centre of each circle. Fold the dough from one side to the other, creating a half-moon. Press down the curved edges well using a fork.
Dust each pie lightly with a little bit of milk and then sprinkle the sesame and nigella seeds over each pie.
Bake the cheese pies in the oven at 180 degrees C for roughly 30 minutes, until golden brown and crispy.
