Thoroughly wash and dry the cauliflower to ensure no excess moisture remains.
Remove the leaves and cut the cauliflower into small florets, discarding the woody lower stem.
Place the florets in a food processor and pulse in short intervals until the cauliflower reaches the size and texture of rice grains.
Heat the olive oil in a large skillet over medium-high heat.
Add the cauliflower rice to the skillet and sauté for 5 to 7 minutes, stirring frequently, until the grains are tender but not translucent or mushy.
Remove from heat and season with salt and black pepper before serving.
