OOOO Great minds! I have done that too!
I also use Cauliflower to make mashed “potatoes”.
You need to towel dry the Cauliflower before mashing and adding butter! SOOO good!
I do that too and love it!
I also make potato salad with cooked cauliflower. It is really good and my husband likes it better than when I use potatoes.
You have to get creative when cutting carbs. LOL
I went to a dinner at a friend’s house. She had mashed cauliflower. It was incredibly good. It tasted like mashed potatoes. Actually even better. I think she said the recipe was from the South Beach diet book.
