Just came back - I agree it is not a foodie culture .. well actually there are good cooks in the Louxor/Assouan region (including the chef on my boat, bless him), but most dishes are borrowed or shared with other middle-eastern countries or North Africa (versions of hummus, tatsikis, wine leaves, oriental styles desserts/biscuits, variations on rice).
Notable exceptions (there might be more, I do not pretend to be exhaustive :) :
- koshary as mentioned earlier in this thread
- Molekheya/Molokhia (soup based on "corete" which is an herb quite rare in western countries)
- Foul and galettes made of foul (Egyptian version of breakfast beans)
- Stuffed vegetables (Mahshi)
- Kunafa : Dessert made with fried noodles (odd I know, but it is good :)
