Ladies who meal prep, what do you make?

I usually end up skipping either lunch or supper because I'm at college. I want to do weekly meal prep so that I can do it on a Sunday and then not worry for the rest of the week, but I can't think of much veggie stiff that will keep for a week without going wilty or weird by Saturday and also survive in an unrefridgerated backpack for a whole day!
