Next time make your own sauerkraut instead of store-bought, it's so easy to make, and there is no comparison between this two versions. Homemade one tastes a lot better, I just made my second bunch. I finished the first bunch within 3 days :-)
thinly sliced, white or yellow
In a medium saucepan, mix together cabbage, onion, salt, vinegar and sugar until well combined.
Cover and bring to a boil over medium-high heat, and cook for about 25 minutes, or until cabbage becomes soft. Stir occasionally.
Remove from heat and let cool for a while.
Serve or place sauerkraut into a jar, seal it well and put in refrigerator for up to a least one month.
