Wash the leek and cut into rings that are not too thin.
Fry the potato noodles in 2 tablespoons of oil - preferably in portions for about 5 minutes each, so that they can all be browned nicely. Remove and set aside.
Then put the rest of the oil in the same pan (if necessary - sometimes what`s left is enough) and fry the minced meat in it until crumbly. Now briefly add the leek to the pan and season everything with marjoram, just a little salt (important because the processed cheese is very salty) and cayenne pepper. Deglaze with 1/2 liter of water. Add the vegetable stock and simmer for about 5 minutes. Stir in the processed cheese spoon by spoon and let it melt in it.
Put the potato noodles and leek mince sauce in a baking dish. Sprinkle the cheese on top.
Now put in the preheated oven (electric stove: 200 ° C, convection: 175 ° C) for about 20 minutes and bake.
Don`t be fooled - it doesn`t look like much, but it`s absolutely filling.
Tip: If you don`t like it that hearty, you can replace half of the potato noodles with ribbon noodles.
