Thanks also to CathyZ for the mashed cauliflower idea. It went perfectly and we are now
fans.
Used "Better Than Broth" & water to simmer the cauliflower, added some of the sauteed onions from the coq au vin, 2 tsp of butter and cracked fresh pepper.
I used a food processor and stopped pulsing when the texture was still a bit grainy. I was afraid of making it "glue-y" like mashed potatoes, so Pam's comment that this won't happen is good to know.
We ate one half of a large cauliflower for the two of us and I could have eaten the entire thing.
