I'll add my 2 cents. I like the suggestion of a raw veggie tray. I would keep it simple with just 2 or 3 different veggies. Maybe carrot sticks, cucumbers, and something red? With dip? Other wise your menu is perfect. I personally don't think you need to add anything at all. People realize they are giving to a cause and don't expect a resturant style meal. Blessings on the mission trip, may it be life changing for all!
