Like many other people, I am having an Olympics opening ceremony party. Unfortunately, I have no ideas for food. Instead of going Russian, I'd like things from a variety of countries. I'd like to have heavy appetizers, such that there is no main course but people still feel satisfied. And because I work long hours and it's a Friday, I'd like make-ahead foods so that I can get a lot in the freezer this weekend. I know, a lot of asks. I'd welcome any suggestions. Thanks!
