Hi! I thought about delivery service for daily cooking too.
Especially for those who are working, have no time to buy groceries, no time to figure what to eat...
If, in a hypermarket, there is a food menu for people to choose from, and are counted as portions.
Say, curry chicken for lunch and fish and chips for dinner, 1 portion each, and they will deliver all the raw ingredients to your doorstep...

One concern will be, will there be increased packaging waste after that...
A solution might be, we provide a reusable containers for the first two times, and for future orders, whenever they order with that particular container, they get a discount, or maybe a free meal, something like that...
(almost like catering service where they have 2 sets of containers and they use them alternately)

This can be done online (online shopping) and offline (buy directly from the hypermarket).

Imagine how much we can do...
1. if it is an app, the menu can come with the recipe and steps to cook
2. we can have season specials like Chinese New Year special, Arabic night special...

Would definitely want to collaborate with someone to make this come true :D
