If you hire someone to do it yourself, you need a canteen, then there are ingredients and some cooking tools. In addition, you need to pay your aunt for cooking. Generally speaking, the cost is still very high. If the company is not big, it will cost a lot of money to cook these light dishes. Of course, unless you consider eating different nutritious dishes or want to give employees better benefits, you can hire someone to cook them yourself.
Customized bento is different. You only need to settle your salary at a fixed time, which saves a lot of trouble and convenience. But there is no guarantee of balanced nutrition and clean ingredients.
To sum up, it depends on the scale of personnel. If there are many people, please ask someone to make it yourself. If there are few people, you can customize the box lunch.
The above hope can help you!
