Lazy cheese pie (without filo)

Crumble the feta cheese using a fork and grate the other cheeses.

Beat the butter in the mixer and add alternating the milk and the flour. Add the eggs and the yogurt. Finally, add the cheeses and the pepper and mix using a spoon.

Place the mixture in a pyrex baking tray and add graviera or kasseri to the top so that it forms a nice crust. 

Bake at 180°C for about half an hour until golden brown.
