Pork Ribs
From Halopedia, the Halo wiki
Pork Ribs are a type of food produced and consumed by humans. It is made from the meat of pigs, which are porcine mammals native exclusively to Earth. They are available as a meal in some ration packs which are given to UNSC personnel. In these, they are served boneless, with barbecue sauce. [1] You can see cans on the table in Halo 2 level 'The Armory' which has pork ribs labeled on the can.
