I read in Family Fun or Family Life magazine about "Momables", homemade "Lunchables". All you need is a tupperware type sectioned container.
My daughters', I have 3, favorites include:

Ham stars (luncheon meat cut with favorite cookie cutter)
star fruit (or other fruit such as grapes or italian plums, or orange sections)
carrot stix
cheese slices
milk or juice

often we will cut chicken cutlets into stars and often we will add a dip for the veggis stix.
