Best way to eat healthy throughout the day in an office?

I recently started an entry level position in an office where we don't always get to take lunch breaks due to how busy it gets. I want to be able to eat healthy though and they do let people snack at their desks throughout the day as long as it's snack foods and finger foods. No access to microwave or fridge. The only thing I can think of is protein bars, nuts, and fruits that can stay in a desk drawer all day like a banana. Any other suggestions?
