2. Practice: Wash and slice the meat first, put it in a bowl, pour a small amount of soy sauce, cooking wine and pepper 10 minute, wash and cut the green pepper, and set aside the garlic slices. Add hot oil to the hot pot. After the oil is heated to 5 minutes, you can add the marinated meat slices, stir-fry and change color, and take out the pot for later use. Reheat the oil, stir-fry the garlic in the pot, then stir-fry the green pepper for 2 minutes, then stir-fry the sliced meat, then add the soy sauce and a little salt, add two drops of balsamic vinegar after coloring, and stir-fry a few times. Dropping balsamic vinegar can make the sliced meat taste tender and smooth.
