Remove the leaves, tough core and cut off any discolored parts from the head of cauliflower.
Roughly cut the cauliflower into 2 inch chunks, then process (pulse) it in a food processor until the cauliflower pieces are about the size of rice grains.
Heat coconut oil in a pan over medium-high heat. Add the cauliflower and cook, stirring frequently, for four to five minutes or until al dente.
Season the cauliflower rice with salt and pepper.
