Trail Food Question (Scout?)

Hi All

I am wanting to make up a "daily ration pack" for a school outing (wild camping) and need ideas guidance as to what can/need/is good for a 14/15 year old for a days food. Needs to be interesting as well as cover off the daily food requirements in a South Africa (10-30 degree C temp range) climate.

A Meal List (B/L/S with snacks) would be great…

Thanks
Mark
