There is a midrash (a traditional teaching) which states that in the Future World there will be a great feast of the meat of the Leviathan. This has not yet happened and will not necessarily be on Passover.
Here are the foods of the Passover Seder.
Pesach (Passover) is important to us since in it we relive the Exodus from Egypt and our birth as a nation, both of which were preparations for receiving the Torah from God.
The highlight of Passover is the Seder meal. This meal is of great importance in Judaism. It is a 3325-year old continuous tradition that began on the night of the Exodus from Egypt (see Exodus chapter 12), and is fully detailed in our ancient Oral Traditions (Talmud, chapter Arvei Pesachim).
The Seder meal is one of those occasions, like Yom Kippur and Hanukkah, that Jews all over the world, Orthodox and non-Orthodox alike, observe in common.
During the Seder, we keep the essential mitzva and customs of handing Jewish traditions down to the next generation, with the traditional Seder foods and the ceremony of reading the Passover Haggadah which retells the events of the Exodus. During all the days of Passover, matzah (unleavened bread) is eaten; while leavened foods such as bread, cake, cookies, cereal and pasta are forbidden. This is a command in commemoration of the Exodus, when the Israelites were in a hurry to leave Egypt and did not spend time waiting for their dough to leaven (to rise). Exodus ch.12.
Certain prayers are added in the synagogue services, and the Torah is read each day of Passover.

Jews eat the Passover meal to commemorate what happen to them a long time ago. In the Bible, it explains that the Jews were taken out of Egypt, in a hurry. Their bread did not have a chance to leaven, and so they ate what they call "matzoh" Now Jews have a meal with "matzoh" in it, to commemorate it.
The Jews eat the Passover Seder meal on the night of Passover (Pesach). It makes little difference whether Passover begins on Shabbat or on a weekday. Note that there are festive meals on every Shabbat, but they are not called "seder" and the foods are different.
Some of them do, and it's not always their fault.
