In a separate bowl, combine the milk or milk sub with the distilled white vinegar and allow it to sit for 5 minutes.
Meanwhile mix together all your ingredients. Whisk in faux buttermilk and taste. Season with kosher salt and fresh black pepper. Chill for at least 15 minutes to allow it to thicken.
Notes
If using a milk substitute, the dressing will not be as thick as regular milk.
