I humbly submit this as my solo-founder, idea-only HN application;
The Standard Pantry.
The standard pantry is literally just that - a pantry of a set of basic ingredients that go along with a range of standard recipes and a weekly menu schedule.
Provide this standard pantry as a partially subsidized offering and teach people how to make a set menu from the basics. Certain components used are refilled at a regular interval as a part of the standard pantry - other ingredients will still need to be purchased, perhaps in conjunction with basic income.
The goal is to help people cook, themselves, more healthy and affordable meals. and overall increase their quality of life.

When I was first learning the basics of cooking from my grandmother, she used to be able to tell me to the penny the cost of each meal we cooked. How some dishes were "$1.43 per person" etc...
It drove home to me the value of cooking and not wasting food.
Cooking is therapy as well. eating well / better is good for every aspect of life.
