R.T.
My daughter takes a lunch box to school and it sits around for a couple of hours before she eats. I put in a cold bottled water or juice box which keeps the contents cool. The healthy snacks I pack in with the cold drink include 1) strawberries with the leaves only cut off; 2) sliced minicucumbers; 3) string cheese; 4) pre-packaged carrots; 5) fat free pudding packs - for the calcium; 6) pre-peeled clementine oranges in a baggie; 7) granola - I like barenaked because it is chunkier and easier to eat with fingers; 8) natural fruit bar or fruit roll up; 9) whole small apple; 10) peanut butter that is pre-packaged in small container for on-the-go.
