I work in schools, too, so I also don't have the opportunity to run out and get something for lunch--not that there is much that I can have in the fast food world, anyway! I always have a salad (usually just lettuce), and usually 2 c. of some raw veggies--celery and peppers are my regulars. Sometimes I will take leftover veggies from my meal the night before, if there are any left. But if you can't count on a microwave, then raw veggies are my go-to. I save my IP packet for later in the afternoon, because I just can't go from lunch to dinner without eating something. I used to get home from work and spend the rest of the evening grazing! Explains how I got to the point of needing IP, huh?
