The Temple Institute reenacted the entire Pesach sacrifice ceremony (which was essentially a nationwide BBQ in Jerusalem).
In olden Days, and hopefully soon again, families would come to Jerusalem, sacrifice a lamb, cook it on the alter in the Temple, and then each family would gather together and eat the lamb for dinner on Pesach night.
As this was a reenactment and not an actual Pesach sacrifice, the meat was distributed to needy families.
Shmot 12:8: “And they shall eat the meat on this night, roasted over the fire, and matzot; with bitter herbs they shall eat it.”
