Place the kale in a bowl with olive oil, apple vinegar, lemon juice, turmeric, cinnamon, salt and pepper.
Massage the kale gently with clean hands for 2–3 minutes until it becomes softer and slightly darker.
Peel and slice the orange.
Slice the apple thinly just before serving.
Add the orange and apple to the kale and mix gently.
Top with chopped walnuts and serve fresh.
