I had left-over boiled cauliflower from last nights dinner. I wanted to try making mashed "potatoes" from it like I had heard in my Weight Wwatchers meetings. It did not turn out as anticipated. So I used it as a soup thickener as I had also heard about in my WW meetings.
I made a beef broth, added some veggies and some creamed cauliflower all for 0 Points Plus (WW system of tracking food).
Blend cauliflower with some water and salt and pepper in your blender.
In a saucepan:
I used 1 C. water
1 beef boillion cube
peas (left over from last night---but you could just throw in some frozen ones)
chopped mushrooms
add in creamed cauliflower from above to make the soup more creamy.
Because the cauliflower was already cooked it took less than 5 minutes from start to finish. It was quite good and you could use whatever veggies you had on hand.
