Cut cauliflower into smaller florets and sprinkle with 1 tablespoon olive oil. Roast on a baking sheet for 35-40 minutes or until tender.
While cauliflower is roasting, put hot wing sauce and sriracha into a small saucepan and heat until boiling. Lower heat and simmer for 10 minutes. Add butter, stir until melted and allow to cool to room temperature.
