I went to a party that served sandwiched that were shaped like fish (little mermaid theme). The mom just made sandwiched and then cut them with a cookie cutter. The adults might like chicken salad in half pitas. You could make and stuff them ahead or let them do there own. You could garnish them with a thin slice of apple to make them look fancy. Or make some other sort of sandwich and use a fancy toothpick to stick then together. Serve with grapes or apple slices or something you can prepare ahead of time and pull out of a ziploc. I also like to serve La Madelines tomato soup which is good and easy to do ahead of time. You could just keep it warm in a crock pot. Hot soup always makes you feel full.
