If you have an ice pack and an insulated lunch box, you could wrap thin slices of turkey or ham with lowfat cheese around a celery stick, or roll them up in a lettuce leaf. Hard boiled or deviled eggs are always handy, too. You could also take along some plain, ff yogurt flavored with sf jello, or stir in some cinnamon, flaxmeal and Splenda. Cottage cheese is a good idea, too, with raw veggies as a dip. And don't forget hummus, that makes a nice dipper for your veggies.
You could take along some Phase 1 friendly soup in a wide-mouthed thermos.
