Sounds like fun, but not sure your friends would really appreciate the Egyptian foods. Your call of course. But if it were my friends I would, 60s themed foods are not my thing. There are so many interesting Egyptian foods it might be kind of fun teaching them about the foods. Get ready to work though looks like they love stuffed breads and vegetables. One dish looked quite interesting, with lentils, rice, and pasta, tomatoes and onions. Tahini, fallafel and breads. Wrapped dates, stuffed dates or just dates. How fun!
All kidding aside, I'd recommend cooking Egyptian food. If you can get your hands on either Arabesque or The New Book of Middle Eastern Food both by Claudia Roden you'll find many Egyptian recipes that are very easy and simple to make plus tasty as well. The ingredients are not difficult to find in local markets. A library is my first suggestion but to get you started here's the master thread with links to our reporting threads, when both books were COTM a few months ago..
