Well, my daughter isn't necessarily 'following' the SB for Kids, but I do try and use my SB for grown ups on her for lunches. Some of the things I give her are as follows:
Triscuits and cheese
baby carrots with ranch dressing in a separate container
cucumber slices (with the ranch dressing)
strawberries
grapes
orange slices
apple
green-tipped banana
melon
NSA applesauce
yogurt (plain, mixed with Splenda and a capful of vanilla...or low-carb yogurt cups, like Blue Bunny - the kids stuff is LOADED with sugar)
cheese sticks or string cheese
cottage cheese
cheese sandwich on WW bread (my dd refuses to eat meat

)
sugar free pudding, made yourself adn put in a small cantainer
crystal light in a sports bottle
cash for milk at school (NO chocolate)
Hope these ideas help!! If I think of anything else, I'll let you know!!
