Swiss chard is a beet-like vegetable with a leafy texture. The stems are crisp and usually red, though they can also be white or yellow. The leaves are dark green to reddish green in hue. With a mild bitterness and a strong earthy flavour, it tastes like beets and spinach. Swiss chard is a nutritional powerhouse, including high levels of vitamins K, A, and C as well as magnesium, potassium, iron, and dietary fibre.
