party lunch pack ideas

I am really growing to love the idea of lunch packs at parties for kids. I think it is such a great way to

get kids to eat their lunch rather than nibble on sweets only. Also, anything they don't eat they can always leave in their lunch box for later or take it home with them. There could always be a dessert table too.

What do you think about this idea rather than a buffet of food and sweets?
