how to store a chicken sandwich overnight for lunch the next day I am currently preparing a chicken breast sandwich using this recipe. However, this is for consumption tomorrow on campus. What's the best way to store this and have it for lunch tomorrow? I only have a microwave so I am thinking if I put it in the fridge and reheat it, it will get extremely soggy. 

How do I store it so that the chicken retains its juices and tenderness (and that the bun/sauces) don't make it super soggy.
I would personally wait with assembling it until right before eating. Put the bread in a bag, the sliced chicken in a bag, and find a small container to keep the pesto in. Then you can assemble and heat on "grill" for a minute or so when you're ready to eat it. That should prevent any sogginess.
