Step 1

Make the Dressing: Add the oil, vinegar, maple syrup, mustard, garlic, and salt to a small mason jar. Seal the jar well and shake vigorously until emulsified, about 20 to 30 seconds.

Step 2

Massage: Add the chopped kale to a large bowl and pour 3/4 of the dressing over it. Use clean hands to massage the dressing into the kale for 45 to 60 seconds, until the kale is tender and has reduced in volume.

Step 3

Mix: Add the parsley, apple, and walnuts to the bowl with the kale and top with the remaining dressing, plus black pepper to taste. Use salad tongs or two large spoons to mix everything together well.

Step 4

Serve as desired; leftovers will keep in the fridge for up to 5 days.
