Heat oil in a large skillet, add the cauliflower rice and garlic and let it cook until the moisture from the cauliflower has evaporated. Start at high heat, and lower the heat once the cauliflower started to turn color and brown a bit. (Toasting adds lots of flavor - burning does not. So watch it closely!) This can take anywhere between 10 to 15 minutes, depending how much rice you're making. Test the consistency of the rice, if you feel that the cauliflower grains are soft, then you know it's cooked.
