Everyone has given you great ideas about lunch. I work in HR and a lot of timess have interviews over the lunch period so I don't always get to sit and eat like a human. I keep cans of tuna, oatmeal, and soup in my drawer. I also bring in yougart, diet jello, carrots, celery, lettuce with me every day. I also don't go more then 3 to 4 (waking) hours without eating something. A piece of fruit, a veggie, etc. This way I'm not STARVING when it' meal time and I don't overeat.
