How about a salad with grated cheese, pieces of chicken, cherry tomatoes, cucumbers, walnuts, onions etc. If you give it time to settle you'll notice just how filling it really is. You could replace the chicken with hard boiled egg for a quick change. You could have a fruit salad for dessert. Bring some dried apricots, dates, raisins on the side. Lots of variations from these and they are very filling.
