Let the frozen cauliflower florets sit at room temperature for about an hour. They will slightly defrost. Rinse in a colander to remove excess ice. Place in the food processor with the knife attachment, and pulse just until small rice-like pieces form. Remove to a bowl. Do the same with the carrots.

Heat the oil in a large skillet. Add the cauliflower and carrots. Add seasoning (other spices can be added, to your taste). Cook over medium heat for about eight minutes or until tender, stirring occasionally. Add tomato paste and continue cooking for another one to two minutes. Remove from heat and stir in a handful or two of parsley.

Cover skillet and let steam to soften. Taste and adjust seasoning if desired. Serve hot.
