In a large mixing bowl, drain the sauerkraut thoroughly. Chop half a medium-sized red onion and mix with the sauerkraut until well blended.

Using a wooden spoon, mix the sauerkraut and red onion together until the mixture is colorful and crunchy.

Cover the bowl and set aside at room temperature for at least 15 minutes to allow flavors to develop.

Transfer the salad to the refrigerator and let it chill for a few hours or overnight for best flavor.

Before serving, give the salad a quick stir and serve chilled as a side dish or topping for grilled meats.
