What do you pack in their lunchbox?

My lvl3 4yo goes to aba 40hrs a week so I pack his lunch everyday. Alot of the things I pack are the same day after day just because I know I cant go wrong with these items plus I don't really know what else would be a good lunch option. At his center they have an airfryer for frozen items and a microwave.

What do you pack in your kids' lunch box? I would love to hear about it and get some different ideas!! Thanks!
