DD starts full days of kindy this year and I realised I have idea what food to send her with. She has a morning and afternoon snack which is fruit/veg but what can i send for her lunch break? Sandwich is an obvious idea but not sure on fillings, it can't be refrigerated and I don't trust using ice locks to keep anything cool. She can't take anything with nuts/possible traces of nuts which rules out all things like muesli bars etc.
I feel like there are lots of obvious options but I'm just drawing a blank so help please.
