Kids Trail mix after school snack what to put in it?

[IShitGlitter]

My DS4 starts full days this weeks at school and am thinking of doing a trail mix for a snack after school seen the idea on pinterest. Has anyone ever made some up? Would it last in a cereal Tupperware container? Am thinking of adding
Cheerios
Pretzels
Cashew nuts
Banana chips
Raisins
Mini marshmallows
The sweet stuff is only a small amount. Here's a pic of the kind of thing am after.

Yes it would definitely last in a Tupperware container

Oh good! Was worried about spending a fortune filling one up only for it to go off or stale.

In the end we got
Dried Banana chips
Cheerios
Pretzels
Dried berries
Raisins
Plain mini rice cakes
Mini marshmallows
Small pack of chocolate chips

I wanted to put a few nuts but dd2 will be having them too so wasn't to sure how she would get on with them. Its filled a huge cereal Tupperware and DS4 is having a little ramekin with our trail mix so can imagine it will last ages.
