Due to long winters, Koreans have developed incredible methods for preserving and cooking vegetables even when everything is frozen outside. Vegetables are a very important part of a Korean meal, often served as side dishes including Kimchi or pickles that have been preserved through fermentation.
Gamja Jeon, Oi Muchim and Sukju Namul are some common everyday side dishes that are completely vegan. Mak Kimchi and Cucumber Jangahjji are also two very popular fermented vegetables that are also often served with meals.
