Method
- Mix the soy, wine, mustard and sugar together. Pour this over the steaks, cover them well and rest for a while.
- Slice the onion into rings.
- Heat the oil in a frying pan, fry the onion rings, then dry them in paper towels.
- Place the steaks in the pan and season with pepper. Turn them over after 30 seconds. If you like steak medium, transfer to a plate now. If you like it well done, cook for another minute.
