Taken directly from here with only adjusting to dairy free margarine. Very simple and tasty!
1/4 medium green cabbage
2 tablespoons dairy free margarine (or more if you are feeling decadent)
salt and pepper
Core and very thinly slice the cabbage. Melt the margarine in a large skillet over medium heat. When it is bubbling, add the cabbage. Salt and pepper the cabbage. Stir occasionally and cook until mostly wilted, about 10 minutes. Turn the heat down to medium-low and let cook, stirring frequently, until cabbage is starting to caramelize (brown), about 10 minutes. Do not let burn. Taste, adjust seasoning, and serve immediately.
