Here is a power point presentation about foods. You can split the class in three groups. A type of food will be on the screen and, in groups, they have to discuss and dicover the food origin. I focused these discussions on simple questions they should ask each other such "is it Spanish?" "No, I think it's Mexican". There will be three options and right below there is the answer.
