Make the dressing: In a small container or bowl, combine the extra virgin olive oil, apple cider vinegar, apple cider or juice, maple syrup, Dijon mustard, minced garlic, and salt and freshly ground pepper to taste.
Place the kale in ta mixing or serving bowl and pour over the dressing. Using your hands, toss and kale with the dressing, and massage the kale as you do this, so that the leaves soften and start to absorb the dressing. Let sit for a few minutes, then toss in the cabbage, combine well and let sit for another 10 minutes.
Then toss in the nuts or pepitas, the Parmesan if using, and any other add ins you like. Serve.
