Side Note: You can squeeze out any excess water from the cooked cauliflower if you would like to. (We did not.) Our frozen cauliflower usually doesn’t have a lot to squeeze off. If using fresh cauliflower rice it in the food processor or shred it on your shredder then place in a microwave-safe bowl and cover with plastic wrap and cook for about 6 minutes in the microwave. Remember the cauliflower will be HOT. So when you squeeze out the excess water use a clean kitchen towel and tongs, not your bare hands.
