Not a school lunch - but a ski lunch!
If you’ve been skiing, you know that buying lunch in the lodge gets expensive fast. So I try to pack our lunch as much as I can. For ski lunches I try to pack in a bit more calories than I do for a regular school lunch. They are very physically active out in the cold, so they burn a lot more calories. I will include more carbs, and even a chocolate treat, in every ski lunch, to just help keep them fueled up for the day.
