1. Defrost the semi-finished frozen steak that you bought, sprinkle a little salt on both sides, pat a few times with the back of a knife, and marinate for 10 minutes
2. Cut the onion into shreds and set aside
3. Heat the pan, add the oil, add the steak, and fry until 3 minutes cooked
4. Use kitchen paper towels to absorb the oil on the medium-ripe steak and cut into small pieces
5. Heat a wok, put a little oil on medium heat, add the shredded onion and fry until the color changes
6. Put in the cut steak pieces and turn to high heat. After the steak changes color, add black pepper sauce, stir fry evenly, and sprinkle with a little salt. Can be out of the pot.
Tips:1. The fire should not be too high when frying the steak, otherwise the steak will get old
2. In the last step, after adding the steak, turn to high heat so that the steak is tender
