Begin by removing the core of the savoy cabbage and thinly shaving the leaves using a sharp knife or mandoline. Place the shaved cabbage in a large mixing bowl.

Core the apples and slice them into thin, even pieces. Add the apples to the bowl alongside the cabbage.

In a small mixing bowl, whisk together the olive oil, Dijon mustard, and freshly grated ginger. Add the apple cider vinegar, and season with salt and pepper to taste.

Pour the prepared vinaigrette over the bowl with the shaved cabbage and apple slices. Toss all ingredients together until evenly coated.

Let the salad rest for about 10 minutes at room temperature or refrigerate to enhance the flavors.

Serve the salad either chilled or at room temperature, optionally garnished with sunflower seeds or nuts.
