While the Hagada tells us about the miraculous way the Israelites after 210 years got out of slavery, there is total silence concerning the question how our forefathers found their way into this bondage. It is true that this story is told in great detail in the Torah itself and the festival of Pesach is one which celebrates our newly found freedom and not our historic troubles, still, it is uncharacteristic of the Jewish tradition to discount this all together when discussing the Exodus in the Hagada.
The Torah does not often give instructions related to food. Besides the Kashruth laws and some Pesach laws there are no instructions how to prepare food or how to eat it. The only remarkable exception to this is the law concerning the Korban Pesach, the Passover lamb.
