Preheat oven to 400°
On a baking dish, add the butternut squash, olive oil, za'atar seasining, salt, and pepper. Toss and bake for about 25 minutes.
Meanwhile, add all the lemon tahini ingredients into a small food processor and puree. If the dressing is too thick, add a little more water at a time until it's at a desired consistency.
Add the cooked butternut sqaush to a small platter. Pour the tahini dressing on top, add the pine nuts, cilantro, and sumac.
Serve and enjoy.
Note: if pomegranetes are in season, add a little on top for garnish, flavor, and holiday spirit.
