Spiralize the apples with a spiralizer (use the fine spiralizer attachment to make thin apple noodles).
Add to a bowl along with the remaining ingredients and combine well (you want the lemon juice to coat all the apple spirals to prevent browning).
Transfer to serving jars.
Optionally: top with coconut cream (leave a can of coconut cream in the fridge overnight, then use the thick cream that settles at the top of the can) and more chopped walnuts.
