Wash the pork tenderloin, parry and cut into finger-thick slices. Season with salt and pepper on both sides and then turn in breadcrumbs. Heat the vegetable oil in a pan, fry the breaded fillet pieces on both sides until light brown and then place in a baking dish.
Add the stock, white wine and mustard to the hot pan and whisk with a whisk. Pour the liquid into the baking dish. Place the cooked ham on top of the individual pieces of fillet. Spread the cheese on top and bake the fillet in a preheated oven at 200 degrees for about 15 minutes.
Spaetzle and fresh salad go well as side dishes. A glass of white wine also goes well with it.
