Just eat anything decent, no reason why you can't just take leftovers such as meat, vegetables etc and just reheat at work, or just take cold (cooked) meat and cook some fresh veg, aslong as you've got basic kitchen facilities you're laughing. Eggs is another easy one, just take half a dozen eggs and some butter, bread if you want and scramble the eggs up.
I quite often take my dinner in and cook it at work, I realise this isn't always possible for everyone though depending on your job circumstances etc, we work a single manned nightshift so it's not easy to prepare food but in between the job it's possible for me to cook a meal. I've been known to do a full roast dinner on nights!

Mind you, manning the pumps and cooking a dinner sometimes leads to a touch of the old over cooked veg and incinerated meat! Beats going hungry though.
For people with no time to prepare/cook at work then things like salads/fruit, cold meat, cheese, hard boiled eggs etc are easy to just shove in a tupperware, much better than raiding the vending machine! Unless you've got a vending machine that does Steak and eggs that is!
