Let's see - skip the PB and J and give 'em ham, cheese and lettuce, or chicken/tuna/egg salad on whole wheat. Pack some cheese and whole wheat crackers. Fruit salad or sliced fruit, veggie sticks with ranch dressing for dip, full fat yogurt mixed with a small amount of jam. Pizza bagels (whole wheat of course) or any variety of stuffed pita pockets. Can they bring soup? A nice veggie and chicken soup, etc.

Hope this helps - I know the difference between what we want them to eat, and what they will eat can be a problem. My two year old goes bananas for pasta - to the exclusion of anything else. I'd worry about it moreif he wasn't growing so fast, and didn't think he'd starve to death!
