Over the Shabbos meal we discussed the idea of sending "Halachikly Complicated" Mishloach Manos. "Halachikly Complicated" meaning foods that cannot be eaten because we have a safek what their bracha is, and therefore cannot be eaten (except for during a meal in which you made hamotzie OR making a bracha on a number of other foods that you otherwise would not eat)
What are examples of such foods?
