What do you keep at work to make for a quick lunch on those days when you can't/don't want to go out? We have a refrigerator/freezer available here at work, along with communal microwaves. Many people keep frozen entrees (like Lean Cuisine) in the freezer, then nuke them.
I'm lucky enough to have an electric hot water pot, so I keep packets of oatmeal in my desk drawer, and sometimes meals like Annie Chun's Soup bowls -- always careful about the high sodium content, though. I'm interested in suggestions that provide variety, or recommendations for convenience products you've tried.
What's in your desk drawer? Please, no lectures/suggestions about how I could make a 3 course, nutritionaly balanced meal at home and bring it in. 1. I'm lazy, and 2. that's a whole other post!
