If you keep a bag of chocolate chips in the fridge at work I can guarantee some of your co-workers will sneak a few. That would be bad enough for any person, but for a celiac, that means their gluteny hands will contaminate the whole bag. It would be better to have individually wrapped chocolate snacks. Or you could get some Lara Bars. They're small but filling, and they're really good. Come in all kinds of flavors.
