In your blender or food processor, add 1/2 cup tahini, 1/2 cup water, 2 tsp miso paste, and 3 Tbsp nutritional yeast. These ingredients will form the creamy base of your dressing.
Next, to the base mixture, add 1 tsp Dijon mustard, 1 tsp garlic powder, and 2 tsp capers. These flavor-packed ingredients will bring your dressing to life.
Juice your lemon and add the freshly squeezed juice to the blender. This will brighten the flavors and add a refreshing zing.
Season with salt and black pepper to taste, then blend until the mixture is smooth and creamy. If the dressing is too thick, add a little more water, one tablespoon at a time, until you reach your desired consistency.
Give your dressing a taste and adjust the seasonings as needed. You may want more lemon juice, salt, or nutritional yeast depending on your preference.
Transfer the dressing to a storage container and refrigerate it for at least 30 minutes before using. This allows the flavors to meld beautifully.
