The main flavor for these Harissa Butter Grilled Cauliflower Steaks is-you guessed it- harissa. Harissa is a North African hot chili paste. It has other spices and garlic in it as well making it really flavorful. So, it's the perfect thing to add flavor to cauliflower steaks- which need a LOT of seasoning.
