Over medium heat, heat the olive oil until hot. Add the cauliflower rice and let it sit for a minute in order to start the cooking process. Add the lemon zest, oregano and cumin. Keep the heat on medium-low so that you don’t burn the cauliflower rice and cook, stirring every minute to 90 seconds to keep it from browning. At the 6 minute mark, add the garlic. Cook for another 2-3 minutes. Season with salt and pepper. Turn off the heat. The heat from the cooking process will carryover and soften the cauliflower rice a little more. If you are not eating immediately, cool the cauliflower rice and store in the refrigerator for up to one week.
