Spread a thin layer of mustard on the schnitzel. Mix the paprika powder with the flour. Turn the schnitzel in it, then place on a wire rack and let the flour layer dry on.
Fry the bacon and onion cubes in the pan, remove and set aside. Fry the schnitzel in the remaining fat for 2 - 3 minutes on each side and continue frying for approx. 4 minutes over low heat. Put the bacon and onion cubes in the pan and heat again.
Serve the schnitzel covered with bacon and onions.
