Recipe Notes

If using frozen cauliflower rice, cook to package directions, usually about 3 minutes. If using fresh cauliflower rice, steam for 3-4 minutes on the stovetop or in the microwave until slightly tender. Take the steamed cauliflower rice and squeeze or press between paper towels to remove the excess moisture and set aside. You want the rice to be fairly dry so your dish isn’t watery!
