Add the garlic, parsley, basil, cilantro, salt, lemon juice, and lemon zest to a mini food processor. Pulse until roughly chopped, scraping the sides as needed. For a smoother dressing, use a blender instead.

Add the olive oil and tahini. Pulse until combined. Add 2 tablespoons of cold water and blend until creamy. Add more water as needed for your preferred consistency.

Taste and add more salt if needed. Lemon and tahini can vary in flavor, so adjust to taste.

Serve right away or transfer to an airtight container. If chilled, stir well and add a little water if needed to loosen the dressing.
