Spicy, sour and savory, kimchi is a boldly flavored side dish that hails from Korea. It consists of fermented chili peppers and vegetables like Napa cabbage. Sound bizarre? It actually undergoes the same process that creates sauerkraut and dill pickles. And if you’ve never tried it, your taste buds (and your waistline) are in for a treat. Kimchi is low in calories and high in fiber.
