I use frozen cauliflower here because the result is a firm texture more consistent with regular rice meaning that it will stand up to stews, soups or any dish with a sauce.
Heat olive oil on medium heat in a saute pan. Add cauliflower and seasoning. Saute, turning occasionally, until the cauliflower is just heated through. Remove from heat immediately and fold in fresh herbs. Serve alone or as an accompaniment with any dish that you would normally serve with traditional rice.
Do not overcook because that will result in mushy cauliflower. Not you or anyone else in your family will like that result. Trust me on this one!
