Rice

Rice is a type of food consumed by humans. It is produced by plants which are native to Earth, which are usually harvested with a massive amount of water in so-called "rice fields" (making it a wheat). Usually, the plant produces "grains" of rice, rather than one massive one. They are available in certain ration packs which are given to UNSC soldiers.

Rice paddies dominated many of the fields just outside of Côte d'Azur on Sigma Octanus IV and on Earth, preferably Asia.
