Which one? The sauerkraut?
I add coconut oil, then chopped onion and garlic to the skillet. Sautee a bit. Add chopped smoked sausage and sautee. Add diced apple. Drain and rinse sauerkraut (I make my own) and add. Optionally you can add a little bit of brown sugar here to increase the sweetness. Caraway seeds are also recommended but I never have on hand so I have never added them.
