Prepare the Creamy Cashew Dressing: In a high-speed blender or food processor, grind the raw cashews into a fine powder.
Add the apple juice, lemon juice, sugar, and salt.
Blend until completely smooth and creamy. You may need to scrape down the sides a few times.
Combine : Transfer the finished dressing to a large mixing bowl.
Add the thinly sliced apples and toss gently to coat them completely, which will prevent them from browning.
Mix the Slaw: Add the shredded cabbage, toasted walnuts, raisins (or cranberries), and scallions to the bowl.
Stir everything together until all the are evenly coated in the dressing.
Serve: Taste the slaw and adjust the seasonings if needed, adding a pinch more salt or a squeeze of lemon juice.
Serve immediately for the best crunch, or chill for 30 minutes to allow the flavors to meld.
