This simple pickled cabbage is a great side dish or accompaniment for any salty Asian rice dishes, bao buns or burgers. It is incredibly simple to make with only 6 ingredients and can be ready in 2 days. Pickled cabbage is a very convenient way to keep some veg on hand to add to a meal without having to prep. It also makes good use of the less attractive outer green cabbage leaves which are often discarded by supermarkets.
