10yo family member decided to become vegetarian. I’d like to gift her a book that explains how to get her nutrients from foods but is age appropriate.

I’m looking for something that would help a child understand vegetarianism. She doesn’t live in my household. I’ve been vegetarian for 30+ years. I want to tell her all she should know but I don’t want to overwhelm her and I also am not there to prepare her meals to help ensure she’s getting all her nutrients. I’m looking for a book that is supportive and explains things in a kid friendly way.
