Any ideas for easy to keep down and nutritious food ideas to make for someone coming home from the hospital?

Something I can make and put in their fridge for them to reheat? And fixings for something for the wife to throw together quickly?

Chicken soup is an obvious one.
What about grilled cheese and tomato soup? I think of that as comfort food. But don't know about the acid in tomato soup for the stomach. And will the cheese be hard to keep down bc it's so thick?

Any other ideas? He's Italian too so any "comfort food" ideas from our Italian bees? I bought pasta fagiole?

Thanks ever so much!
