Preheat oven to 450F (recommended to use convection setting, if possible)
On a sheet pan, mix together chopped carrots, chopped onion, whole garlic bulb, oil, cumin, curry powder, and salt. Spread in a single layer and roast for 15-20 minutes, until vegetables are tender.
Peel the garlic skins from each of the cloves. Discard the skins. Transfer roasted vegetables to a bowl along with the roasted garlic, tahini, worchestershire sauce, and apple cider vinegar. Blend until smooth. OPTIONAL: For a thinner consistency, mix with milk, coconut milk, or chicken/vegetable stock.
Reserve some of the sauce for dipping the cauliflower. Toss the remaining sauce with cauliflower. Spread on the same sheet pan and roast for 15-20 minutes, until cauliflower is crisp on the outside and tender on the inside.
Serve with reserved sauce for dipping. Enjoy!
