How about some mild chili with bread or muffins? Chili is very healthy and the leftovers reheat well. Even one of those grocery rotisserie chickens with homemade sides would be good and provide sandwiches the next day. For fun you could also bring a bottle of the non-alcoholic sparkling cider to make their meal a little more special. I'm sure they will be thrilled with anything!
