Bring a medium pot of water to boil and add the sweet potato. Boil until tender, then strain and set aside.
While the sweet potato boils, heat the avocado oil over medium heat in a large skillet and add the sausage. Brown on each side for about 3-4 minutes or until lightly crisped. Set aside.
Add the apple to the skillet and saute for 2 minutes or until lightly fork tender. Add the cabbage, salt, and pepper and stir to combine. Pour the broth over the cabbage and cover the skillet, allowing the cabbage to wilt over medium-low heat for 5-7 minutes, removing the lid every few minutes to stir.
Once the cabbage is wilted, add the sausage, boiled sweet potato, and red wine vinegar and stir to combine.
Serve topped with chopped parsley
Notes
To make AIP, use ground pork or turkey instead of sausage and season with herbs of choice.
