Face it: if you're the cook in the family and you're having surgery, or if you're the cook in the family and you'l be overseeing someone else's recovery, you'd better have the food prepared in advance. It had better be easy to reheat, serve and eat. It needs to be appetizing. It needs to be easy. Of course it has to meet dietary guidelines for recovery, and that's a wild card for purposes of this discussion.
We don't seem to have a dedicated topic for this purpose, although we have a couple of topics that are relevant:
Batch Cooking: One large batch, many small meals. Share your ideas!
...and this old one, which takes into account feeding the entire family but got to be rather specific about the surgery in question:
Food ideas for friends after major surgery?
What are some of your ideas for meal prep and serving when there simply won't be time or energy for cooking? Got any favorite recipes? If you've been through this, what worked and what wouldn't you recommend?
Packaging ideas are also welcome.
