Cauliflower rice is a low-carb and gluten-free alternative to regular rice. Start by pulsing cauliflower florets in a food processor until they resemble rice grains. Heat a skillet with some oil and sauté the cauliflower rice for a few minutes until tender. You can add garlic, onion, or spices for extra flavor. Cauliflower rice is a great side dish for stir-fries, curries, or salads.
