How to make
In a bowl, mix the mayonnaise with the yoghurt to a homogeneous mixture. Put some of the mixture at the bottom of a large bowl.
Grate a potato on top, grate feta cheese on top of it and then an egg. Add in more of the yoghurt mixture. Continue in the same order until out of ingredients.
Pour on the remainder of the mixture on top, grate your last egg and cheese.
