Final answer:
Roasted meat is avoided at the Passover seder due to its association with the Paschal lamb sacrifice, which ceased after the destruction of the Temple in Jerusalem.
Step-by-step explanation:
Roasted meat is not served at the Passover seder because it is reminiscent of the Paschal lamb, which was traditionally sacrificed and roasted on the eve of Passover in the times of the Temple in Jerusalem. Since the destruction of the Temple, the Jewish people stopped this practice to observe the holiday without sacrificial offerings. The seder meal includes foods like matzoh (unleavened bread) and haroset, a sweet paste made out of nuts and fruit, which serve as symbolic reminders of the hardships and the redemption experienced by the Israelites in Egypt.
