Sashimi is a raw dish made with thinly chopped fish/meat and is traditionally served with soy sauce.
“Sashimi” is only the fish, though it can also be similarly-prepared meat. Meat is not often offered outside of Japan, however. It is most commonly raw fish, sliced thinly. As established, it is not paired with other ingredients, except soy sauce if desired. This prevents other ingredients from marring the flavor of the sashimi.
