Every time camp rolls around my coteachers have tried to pressure me into doing something cooking related for camp. It is not that I am set against it, I just do not see how it is feasible. Where would the ingredients, equipment and assistance in translation come from? In the past, coteachers have tried to name dishes that they think are easy and would not require special things, but these usually amount to the same list of foods people here seem to think foreigners eat every day (sandwiches, pancakes, cake, etc).
What foods did you have in mind? Does your school already have some cooking equipment on site? What kind of budget is your school willing to provide?
