Drain the water from the cashews and place them into a high-powered food processor. Add in all the remaining dressing ingredients and start the blender on the lowest speed, slowly increasing the speed into it's at the highest speed.
Blend all the ingredients until smooth and creamy. This will take a good 2-4 minutes and you'll need to stop and scrape down the sides every so often.
Add all of the salad ingredients into a very large bowl. Add in the dressing and toss until all the vegetables are evenly coated.
Cover and refrigerate for at LEAST 1 hour (this helps the broccoli absorb all the flavor) or up to overnight.
Once chilled, taste and add and salt and pepper if needed. Then, DEVOUR.
