One of the teachers at my son's school sent us this link:

It has some good suggestions and links to good suggestions, if you can get past the preachy tone :)
Things I have made for my kiddos- hummus and pita chips/carrots/green pepper, mini sweet peppers (the yellow and red ones that look hot, but are not) stuffed with cream cheese, celery sticks with peanut butter or cream cheese (remember "ants on a log?"), bagel with a little marinara and mozzarella under the broiler for a pizza bagel, quesadilla with mild salsa, pb&j rolled up in a tortilla and cut into "pinwheels," Tasty Bite microwave pouches with pita chips, apple slices with cheddar cheese melted on in the microwave (yummy, don't knock it till you've tried it), greek yogurt with chopped walnuts or sunflower seeds and maple syrup. My kids like anything that they can dip into or sprinkle something onto, so you may see a theme above!
