Tasty, Healthy, Easy snacks for hospitals?

So to make a super long story short... Someone is in the hospital, tragically, and will be for months... His family and friends are all staying at the hospital, eating out of vending machines. I want to be able to make tasty, healthier food for them that they can eat cold/room temperature and don't need to heat up as there are no microwaves and whatnot. Give me some ideas? Perhaps even some involving chicken?
