Famous russian dish - "French meat"

What can I say? Russians love this dish, it's actually a casserole .
Pretty easy to make.

Here what you need -
3 potatoes, peeled and cut in thin slices
2 onions, peeled, cut in rings (devidev into 2 portions)
400 g ground beef (pork)
100 g mushrooms, cut
100 g shredded cheese
3 tbs mayo
salt, pepper
olive oil

In a deep backing dish, covered with foil and greased  put the layer of potatoes, add salt and pepper.
then a layer of 1 portion of onion rings, then a layer of mushrooms, a layer of mayo.
Next layer is meat but before that mix it well, add salt and pepper.
and put it in one layer spread it all over your mayo layer
then another layer of onion rings.
Cover all your layers with foil, preheat the oven to 400 degrees and bake your creation for 35 minutes.
After that, remove the foil and put shredded cheese all over your casserole, bake another 15 minutes or until the cheese is golden brown.
I would advice to serve it with vegetables - like green beans, corn and tomatoes.
