Make dressing: In cup of smoothie maker, combine olive oil, apple cider vinegar, maple syrup, tamari or soy sauce, mustard, and ginger, and pulse until completely blended. Taste and season with salt & pepper if needed (but keep in mind the tamari is already salty).
Make salad: Place kale in salad bowl and pour a little bit of dressing over it. Massage the dressing into the kale with your hands (this helps the kale to become soft and absorb some of the dressing). If you are using other salad greens, add them afterwards (they don't get to be massaged, poor things). Add the carrot and apple. Season lightly with salt & pepper.
Finish salad: Pour the rest of the dressing over the salad and toss. Top with toasted walnuts and grated gruyere. We also topped ours with two poached eggs each to make a hearty dinner salad. Enjoy!
