This is my Mom's variation of the classical Bulgarian Moussaka (which I have also posted). It might have more steps but it's easier to bake. Cooking time includes boiling the potatoes while you fry the chicken.
Boil the potatoes, peel them and smash them in a bowl together with the butter and some salt and add enough milk to get a soft but by no means liquid mass (in fact its up to you to decide how thick you want it to be).
In a frying pan put the 2 tbl oil, the chicken, the tomato paste, cumin, pepper, nutmeg and some salt and start frying dividing the meat with a fork until it starts to fall apart into crumbs.
Grease a baking tin with the remaining oil (dont forget the sides too), spread half of the potatoes on the bottom, pour the chicken over them and cover it with the remaining potatoes.
Preheat the oven to a medium temperature and put the moussaka in and let it heat for 5 min.
In a bowl beat the yogurt with the eggs the thyme, a bit of salt and some black pepper.
Pour the yogurt mixture over the moussaka and bake until it gets golden brown (about 10-15 min).
When ready take out of the oven and leave to cool a bit potatoes cool very slowly.
