Wraps are also good, expecially if you pack the tortillas and fillings seperately, and they can be prepared the night before. A favorite of mine is leftover roast beef with horseradish cheddar, greens, tomato and coriander mayo. If they like onions, some mandolined red onion is great also. Another thing that came to mind when reading about the babaganoush, is sending it with a portion of the little pita-ettes and some crudites. Toss in some chips and fresh fruit, and call it lunch...
