If you can make a meal in 20 minutes, but it takes you 3 hours to clean up, that doesn't count as time-saving...I was also interested in what the fantastic Alice Hart says in her wonderful The New Vegetarian (which is, in case you were wondering, an entirely new book, not a repeat of her also-wonderful Vegetarian), that very few people can really really plan a week's or more worth of marvelous meals very well. In other words, if you have the time, it's certainly not bad just to relax and plan and source fewer meals at a time! I had to do that in Manhattan, because I couldn't carry home a zillion bags from the shop, even though it was just downstairs. Besides, it was so easy to stop into the wonderful shop, which was not only next to my apartment building but to my subway and bus stops, and of course I got fresher produce in the house that way.
Mr. Smith in the same article also speaks of how it's wise to adjust the way you eat to how you're feeling, which of course can vary day to day -- another reason not to plan and source all at once, unless of course you want or need to do so....
By the way, Ms. Pleasant's magazines have the most beautiful food photography and kindest writers! who stand up so strongly for what is right. Here's the one I mention above: https://www.originmagazine.com/ .
