I like the fabric lunch boxes that come with a pouch to slip a freezer pack into that keeps the lunch cold. Maybe you could do little sandwhiches made of up deli meat and/or cheese on crackers. Or use cookie cutters to make different shapes from bread. Cheese stick, some cut up fruit that she likes, or baby carrots, celery, or grape tomatoes with ranch dip or hummus if she likes them.
