I used to have to prepare these kind of snacks for the kids (5-12) at after school care. They used to go mental for just carrot sticks, water crackers, a dip (we used to buy french onion soup powder and mix it with sour cream) and just cubes of tasty cheese. then after that some sliced apples and oranges.
I mean the kids loved it, no idea why. We used to give them like honey, jam, vegemite or cream cheese sandwhiches.. then next day strawberry or vanilla flavoured yoghurts and sliced fresh fruit.. but they LOVED the cheese, dip, carrot sticks then sliced fruit.
