Potato Roll with Mushrooms

A baked potato-dough roll filled with sauteed onion and mushrooms and grated yellow cheese.

Ingredients

First make the potato dough: boil the potatoes and mash them well as if making mashed potato. Mix them together with the three tablespoons of flour and the three eggs. Knead the dough by hand and then spread it out on a cloth, aiming for a rectangular shape.
Over the potato layer grate half of the yellow cheese, then make the tasty filling by lightly sauteing the onion, the chopped mushrooms, the salt and the black pepper in a little butter.
Place the ready filling right in the middle of the potato dough sheet and, helping yourself with the cloth, start rolling it into a roll. Then transfer the roll to a tray and pour a little melted butter over the top - it is good to first make small cuts on it with a fork or knife.
Finally sprinkle breadcrumbs on top and place in the already hot oven, where it should bake for about ten minutes.
When you take it out ready and baked, sprinkle it with the remaining grated yellow cheese.
Return it once more, for the last time, to the oven and leave it until the cheese melts. Then take it out, leave it aside a little to cool so it does not stick when slicing, and then enjoy it.
