Prepare the potatoes with the onions and spices for fried potatoes. Then put the whole thing in a baking dish.
Season the minced meat and spread it over the potatoes (you can of course fry the minced meat until it is crumbly, but it is not necessary).
Then place the cut tomato slices on top and sprinkle with chives. Put on the semi-hard cheese and a few flakes of margarine. Bake in the oven at medium heat (180 ° C) for about 30 to 40 minutes.
