Steam the cauliflower for 8 minutes and then let the head air dry.
Use ½ the tahini dressing to glaze the cauliflower and reserve the rest for garnish.
Using a pairing knife, make tiny slits all around the cauliflower and insert pieces of the sliced dates.
Roast the cauliflower at 450F for 10-15 minutes, depending on the size of the head.
Broil the cauliflower until crispy. You may need to cover the hot spots with tin foil and rotate the cauliflower while broiling.
Top the roasted cauliflower with the remaining tahini dressing, toasted pine nuts, and parsley.
