Salt and pepper the turkey schnitzel. I seared them briefly. Clean the leek and cut into rings. Steam briefly together with the water. Add the processed cheese and cream (or condensed milk). Deglaze the whole thing with a good dash of wine.
Put the turkey schnitzel in a baking dish and crumble the defrosted hash browns over it. Then pour the leek and cheese mixture over it and place in the oven for about 25 minutes at 180 degrees.
