Good morning, 5 a.m. here.

I've never tried cauliflower as rice. What a good idea. It works great as potato salad. I'm going to try cauliflower rice this afternoon with chicken ala king.

For the person who was looking for a potato salad recipe here is mine.
Fresh cauliflower cut into bite size pieces and microwaved until cooked but not mushy. Let cool.
add green onions, chopped hard boiled eggs, mayonnaise and salt and pepper.

Adding a little vinegar kicks up the flavor but it's good without it too. I served this to my Mother, who loves potato salad, and I had to tell her it was cauliflower she couldn't tell the difference.
