If it were me, I'd send in a "kid friendly" healthy snack, such as a veggie and dip(carrots and organic ranch dip, or similar).
Most kids love carrots and dip.
How about organic cheese and crackers?
Grapes(cut in half) and yogurt tubes(organic) - kids love grapes!
And so on...
I completely understand your dilemma and way of thinking. My DS is sensitive, too, and we don't do junky foods and snacks, especially ones with food dyes. It bothers me to no end to see these kids sent to school with pure sugar and dyes in their lunch boxes every day. Ugh.
I've found when I have to supply food to an entire class, I have to step back and figure out a healthy yet friendly alternative to the junk so many of them are used to. I doubt very much many of the kids would actually eat stuff that we like at home, like hummus, etc.
