Beat the schnitzel, season, flour and fry on both sides.
Put the schnitzel in a baking dish like flakes and place a slice of Emmentaler in between. Make a stew from the remaining fat and flour, pour in the broth, stir in tomato paste and season to taste. Add the sour cream and pour the sauce over the schnitzel. Bake in the preheated oven - convection 180 ° - 45 minutes.
This goes well with mashed potatoes or pasta and salad.
