How to cook
Break up the broccoli into small pieces and boil them in salted water until they soften.
Put a little melted butter in a bowl and arrange the boiled and sliced potatoes and the broccoli on top of them.
Place the mushrooms on the broccoli and grate the white cheese. Sprinkle with black pepper.
Make a topping of the yoghurt with eggs and pour it over the products.
Place the casserole in the oven and bake it for about 20 -25 minutes.
Take it out and grate the smoked yellow cheese on it, put it back in the oven and bake it until the yellow cheese melts and acquires a golden crisp.
