Defrost the frozen cauliflower by running warm water over it. Drain well, and pat dry with paper towels.
Put the cauliflower in your food processor, or use your blender on the "chop" setting. Pulse a couple of times until the cauliflower is small like rice.
Heat 1 tbsp. olive oil in a skillet. Add cauliflower, onions and carrots. Cook until veggies are almost done.
Season with 1 tsp. seasoned salt and 1/2 tsp. black pepper. Cook for a few more minutes until the cauliflower starts to brown, stirring frequently.
