Start with one of these. I dump mine in a pint-size Bell or Mason jar.
Add 1 cup of this. It's a bit on the salty side, so I add the cracked pepper here as well.
Pour in 2-4 T of this, and shake the bejeebers out of it. The viscosity of the mixture is really personal preference - I use less for a veggie dip, more for a ranch-style salad dressing.
Refrigerate for at least an hour, and enjoy. Hey, the dressing is vegan/vegetarian, not my salad. 😉
