A No-Yeast Feast is a type of meal that does not include any yeast-based ingredients. It is often associated with the Jewish holiday of Passover, known as the Seder, which is a ritual feast that marks the beginning of the holiday. The term 'Seder' comes from the Hebrew word for order, and it refers to the order of the rituals and readings that are part of the Passover celebration. A No-Yeast Feast is a traditional part of the Seder, and it is meant to symbolize the haste in which the Israelites left Egypt.
