Need Suggestions---Celebrating Multi-Culture?

-I teach children ages 3 to 5yrs old and we are celebrating Multi-Culture this week. We have to ask for donations from the parents by bringing a dish (purchased from a vendor only). The country we are celebrating is Egypt but I'm not sure of what to ask the parents to bring. Egypt Cuisine is more of lentils, okra, breads, hummus, pita breads, fish, potatoes, carrots, veal, beef. All foods that kids would usually turn their noses up too!Seriously? What are the kids supposed to learn from this? What an abstract concept, unless your kids in class are from that region. And you are asking much from the parents. Some 'multicultural' foods are very expensive, and kids not familiar with the food will snub the stuff. Our taste buds are made for 'our' foods. Coca'Cola, for example, has formulas to march tastes for different countries around the world. Our Coca-Cola is nice and sweet compare to the more bitter 'Italian' version of Coke. Sounds more like 'Multi-Culture Week" is more like a biased tourist approach to developing an appreciation for people not like them. Our school does 'cultural foods', and I feel it is more 'biased' and 'stereotypes' of a culture. As a teacher, I think this has no value for the class. As a parent, I would politely say, "Sorry, I will not participate."
