The mutton roll is taken out in advance and thawed. It is best to use a microwave oven. Naturally, the thawing is slow and it is not easy to open in the pot.
Add oil to the pot, add pepper and half of the scallion, and sauté.
Put in hand-teared green pepper pieces, carrot slices, stir fry.
Add the mutton roll and stir fry. For better quality mutton rolls, add water if appropriate.
Add the sauce adjusted in advance: sugar, vinegar, soy sauce, cooking wine, oyster sauce, salt, mix thoroughly and pour. Because of the salt in the oyster sauce and soy sauce, the salt should be kept less.
