We put in whatever fruit is in season. Most keep ok in a small sealed container in the bigger lunchbox till lunchtime eg mandarin already peeled, cut up orange etc. Dd1 loves getting kiwi or passion fruit cut in half with her own spoon for scooping. We do sandwiches, (usually Vegemite- she's less adventurous for school than home lunches) and cheese cut off the block into 'cheese sticks' or yogurt in a tightly sealed container or pouch. Would love to do more home made stuff though, even plain plain pop corn maybe but muesli slices etc too. Hoping to read some ideas : )
