Evening Shifts- what to do for dinner?

Today I brought left-overs - Smoked Sausage and potato wedges. Also, watermelon and celery for snacking. I keep peanut butter at my desk and so I put some on the celery. I also like bringing morning star black bean burgers and just microwave them for a few minutes and eat them with thin whole grain buns and a little salsa and avacado. Sometimes I bring rice or soup or frozen dinners. I have herbal tea at my desk, too and I try to go for that instead of soda or other stuff. I usually try to bring left-overs or a simple pbj but on days I forget lunch Subway is right next door.
