Neither my husband or I like cauliflower, especially rice. I took a chance and made this. My husband said, “This is great. What kind of rice is this that allows us to eat it?” We are on low carb and he thought it was real rice! We both fought over who was getting the leftovers. ๐ Needless to say, this was great!! Definitely making it again.
Love it! Thank you so much for taking the time to share this. Iโm so happy you both loved it!โค๏ธ
So good!! I added chopped spinach as you suggested. I didnt have cream cheese or yogurt, so I blended 1 cup of low-fat cottage cheese instead. Everyone loved it so much!! Thank you for sharing your recipe.
Thank you for taking the time to share! So glad everyone loved it!๐
