Preheat the oven to 450°F or air fryer to 400°F. Line a baking sheet or the inside of your air fryer with aluminum foil.
In a small bowl whisk the tahini, water, apple cider vinegar, garlic, thyme, salt, cumin, and cloves.
Place the cauliflower on the baking sheet or in the air fryer. Brush half the tahini mixture on the cauliflower. If using the optional extra veggies, toss them with 2 tablespoons of the mixture. Roast for 40 minutes.
Remove the cauliflower from the oven or air fryer and carefully brush on the remaining mixture.
Place back in the oven or air fryer and roast 10 minutes more.
Cut into wedges and sprinkle with additional fresh thyme.
