If you have a Vitamix, you can make this in 10 minutes! If you don't, you will need to soak the raw cashews overnight (8-12 hours) in some water, drain and rinse.
Add all of the ingredients, reserving 1 tablespoon of the sweet pickle relish to stir in after blending to a high-powered blender.
Blend on high until 100% smooth, scraping down the sides a couple of times during.
Pour into a bowl or jar and stir in the reserved pickle relish.
If you would like a kick to your dressing, add a pinch of cayenne.
Serve over salads or as a veggie dip.
