A bento (弁当, bentō) is a single-portion take-out or home-packed meal of Japanese origin. Outside Japan, it is common in other East and Southeast Asian culinary styles, including Chinese, Korean, Singaporean cuisines and more, as rice is a common staple food in the region. A traditional bento may contain rice or noodles with fish or meat, often with pickled and cooked vegetables in a box. Containers range from mass-produced disposables to hand-crafted lacquerware. Often various dividers are used to separate ingredients or dishes, especially those with strong flavors, to avoid them affecting the taste of the rest of the meal. A typical divider is green plastic grass (referred to as ‘sushi grass’ in the United States). This also works to stem the growth of bacteria.
