Recommend me some non-microwaveable healthy meals I can use for lunch at college please!

I don't have a way to heat up food at school and would like to eat more healthy while I'm at it. I'll try anything. I really like eating aisan styled meals as well so if you can recommend me anything like that that doesn't have to be heated, that would be awesome! But yeah, I'm open to anything, not just aisan based food xD

Bonus pikachu bento box image because this is awesome and images on blogs make it look more pleasing! (in my opinion at least)
