Pick the dates you want to plan meals for.
Enter one meal at a time. They will be ready to put on days in your new plan.
Put this plan online so you can open it on your phone, and so whoever you cook with can edit it too. No accounts and no sign-in — a link is the key.
Anyone with the link can view and change the plan, so send it to people, not to the internet.
Scan it with a phone camera to open the plan there.
