Chard is a leafy green vegetable similar to beets. It’s not yet that popular in the United States, but with the interest in healthy diets and in replacing as much meat with healthy vegetables as possible it’s gaining in popularity.
It’s mostly used in making salads, soups and omelets. Even though it’s known by the name Swiss chard as well it’s not known where it originates from, but it’s definitely not in Switzerland. The first colonist brought it in the US and it’s been grown here ever since.
