3. Add oil to the pan and fry the meat.
4. When the meat is deep-fried until golden brown, remove it with a colander.
5. In a separate pot, add the yellow pepper and red pepper and stir fry.
6. Add the fried tenderloin and stir fry.
7. Pour in the prepared sauce (tomato sauce, white vinegar, white sugar, cold boil) and stir fry.

Tips:1 The tenderloin should be used for sweet and sour pork, which is easy to cut and does not contain white meat, and tenderloin should also be used for sweet and sour tenderloin.
2 Sauces (3 spoons of tomato sauce, 1 spoon of white vinegar, 1 spoon of sugar, 50 grams of cold white)
3 Don't save cooking oil when making this dish. If you put less oil, the meat will not be crispy.
