Get a plastic air tight container and make up a salad the night before. You can even buy veggie chicken strips to add to the salad. I use these and they are really good.

I'm not a big fan of real meat, but I do like Tofu and veggie meats. Maybe boil up a few eggs, take shells off and keep in the ref. to add to your salads. It's an excellent source of protein to keep you mentally allert. Same as cheese and Tofu. Feta is my favorite in a salad.
