Go for variety. Buying the fruit and vegetables your children like assures that they’ll eat plenty of them but what about trying the ones they’ve never even heard of? How about jicama, papaya, tomatillos, mango or even artichokes? It’s always a good idea to look for what’s in season: it will be fresher and may even pack in some extra nutrients. Prewashed and peeled veggies, such as mini carrots or celery sticks, make great snacks. Apples, pears, peaches, oranges and bananas are lunchbox-ready, but any fruit is easy to pack—simply cut it up and put it into little single-serving containers.
