How to cook
Slice the bread into bites. In a bowl, whisk the eggs with the yoghurt, baking powder, oil and feta cheese. Mix with the bread bites.
Place the resulting mixture in a greased oven dish. Spray the bites with some milk on top and add pieces of butter on top.
Bake in a preheated 356°F (180 °C) oven, until browned.
