Combine all the ingredients except the olive oil and mix well.
Using a whisk, add the olive oil in a thin stream whisking the whole time. Taste often and adjust the seasonings. If it’s too bland, add more vinegar, salt or miso. If it’s too sour, add more honey or maple syrup or dilute it with a little more olive oil...
This dressing will keep for at least 1 week in the fridge. I keep mine on the counter because we go through it fairly quickly. When kept in the fridge, the olive oil and tahini may thicken, take it out and allow it to warm up at room temperature before using.
