Here in the north, planning for Sukkot requires consideration of the temperatures, especially when Sukkot is in October. This year, Sukkot starts in September, so we may not be such Frozen Chosen this year. Even so, the evenings are definitely crisp, so soups and stews are some of the best foods to serve during the feast. I recommend planning at least a week in advance so you don't need to worry about your menu items during the feast.
