My daughter is in elementary school and gets breakfast most days and lunch everyday. They seem like standard school lunches from my childhood - chicken patty sandwiches, pizza on fridays, tacos, and such. If they don’t like it there is a “fun lunch” which is usually like pb&j, a muffin or something else more plain.

There were some folks from our local high school who did a presentation for our parent group and they said the kids are always hungry, school lunch or not. Just the amount of time they may go, how short lunch breaks are, how lots skip breakfast and growing bodies. I’m sure it’s hard to keep them well fed, but wonder if the schools need to be more lenient about snacks or something.
