Ideas for packed lunches

Hey mommies! My daycare has recently requested I pack a lunch for my little two days a week. I’m struggling with veggies and proteins and looking for ideas. It can’t be refrigerated or reheated.

To make it harder it seems like she’s gotten really picky lately. Almost a separate issue but lately she refuses to even try a bite of things some things. She’ll eat two bites of dinner then say she’s done and ask for Cheerios and raisins. I swear she’d live off that and cheese if I let her.

She used to be great at eating veggies but feels like a struggle lately so I don’t know what veggies she’d be willing to eat cold. Proteins I only really have hummus, cheese and diced ham. She likes most fruit so no issues there at least. Thanks!
