Preheat oven to 400˚F. In a small bowl combine olive oil, spices, salt, and sriracha. Stir to combine.
Cut cauliflower into florets and drizzle with about half of the spicy sauce. Stir to combine and spread out on a large baking sheet.
Bake cauliflower for 30 minutes. Stir the cauliflower every 10 minutes to ensure even cooking. Drizzle the rest of the spicy sauce on near the end of the cooking time so it is fresh and doesn’t burn.
Serve roasted cauliflower with lime wedges, garnished with cilantro and serve with yogurt dipping sauce.
