Wash and slice the kale. Transfer the sliced kale into a medium-sized bowl.
Sprinkle the apple cider vinegar and a tablespoon of salt on top of the kale. Use your hands to rub the kale against each other for about 2 to 3 minutes. The kale leaves should feel soft to the touch and should have reduced in volume once you are done.
Arrange the Kale on a plate. Top with walnuts and the finely chopped onion. Drizzle the dressing (recipe below) on top and let sit for about 10 minutes then serve.
CREAMY AVOCADO DRESSING
To make the dressing, use a food processor or blender to mix avocado, minced garlic, olive oil, juice of half a lemon, salt and pepper. In case you do not have a food processor, use a medium-sized bowl and a whisk to whisk everything together, until creamy.
Drizzle on top of the massaged kale, allow it to sit for about 10 minutes then serve.
Notes
Be careful not to massage the kale for too long to prevent it from turning soggy.
