Here are some lunch ideas from an article I found at ivillage. You can substitute low-fat versions for some of the items and skip the tomatoes since your daughter can't eat them. Hope this helps.
10 Change-of-Pace Lunch Ideas
1. Date-Nut Bread with Cream Cheese, Celery Sticks, Whole Apple, yogurt-Covered Raisins, Milk
