Add all the ingredients to a bowl and mix until well combined.
Serve immediately, or for best results, cover and refrigerate for a minimum of 2 hours before serving.
Notes
Cool Mixing Trick. Make sure your vegan mayo is at room temperature before mixing. Cold mayo can be a bit stubborn, but room temp mayo blends like a breeze.
Shake, Shake, Shake. Give your dressing a good shake or stir before using. It's like waking up the flavors, so every drop is packed with yumminess.
Chill Out. Let your dressing hang out in the fridge for a couple of hours before using. This helps all the flavors get cozy and mingle for an even better taste.
Customize the Creaminess. Want your dressing thicker? Use less plant milk. Need it a bit thinner? Add a touch more milk.
Adjust Flavors to Your Liking. Want more garlic powder or extra parsley? Add what you like. If it's tangier than you prefer, add 1-2 tablespoons of plain vegan yogurt to balance it out.
