Break the cauliflower into florets. Using a cheese grater, grate the cauliflower. Or, if you have a food processor, add florets to the bowl of your food processor and pulse until cauliflower looks like rice.
Heat a large non-stick skillet over medium heat. Add the coconut oil. Once the oil has melted add in the riced cauliflower and cook for 3 to 4 minutes.
Add in the coconut milk , lime juice, and zest and mix well. Cover with a lid and let steam for about 10 minutes or until the coconut milk has been absorbed.
Stir in the chopped cilantro and season with salt and pepper.
