Vegan

You live in the country, but don't drive for environmental reasons, yet you are considering using Door Dash? Can we also assume you don't want to face the obvious answer: stockpile or grow food and cook for yourself?

I don't mean to be overly critical, but it sounds to me like you are trying to avoid compromising on both your ideals and modern day expectations, to find a practical solution. Your pre-industrial agricultural ancestor would have spent a week stockpiling food in the root cellar, by scrounging around locally, or going very far to stockpile food. They probably were also farming animals in a significantly more sustainable/humane way, though certainly exceedingly scarcely.
