Hi Elxr. Welcome to the beach
I love the cauliflower (CF) "mashed potatoes. I add I Can't Believe It's Not Butter and Mrs. Dash for some spice.
My favorite variation of this is to add some frozen spinach to the frozen CF, cook until very soft. Place in an a casserole dish and mash. Add the I Can't Believe... and spices. Then top with shredded mozzarella cheese and heat in the oven until the cheese is melted. This can also be done in the microwave.
I usually divide this up into individual microwavable containers and top with the cheese. So easy to take to work along with some leftovers from dinner the night before (such as chicken breast, salmon, sirloin burger patty, etc).
