Tips

Eggs should be cooked and peeled in advance.
Green beans can be cut into sections before blanching.

Dazang mustard sauce has a strong salty taste. If it is bland, you can reduce the amount when applying it.
If you like to eat hot food, you can warm it slightly in the microwave or oven before eating.
