Balanced healthy food menu suggestions for a 12 year old child

Thank you for your suggestions for breakfast. It is very easy to find ideas for babies and young kids, but I did not find much for older boys. I have used some of them and the boys are doing better.

I now want suggestions for balanced and healthy food menus for my 12 year old. He is very active and takes part in most school sports plus after school clubs and I would like to cook healthy dinners. (Jenny)
