There's nothing wrong with taking short cuts for a soup!
I used to always use a fresh head of cauliflower, wash and chop it down to make this soup, but recently, I made this soup from frozen cauliflower florets-- I could not taste the difference between using fresh vs frozen, so from now on, frozen cauliflower it is! It makes life so much easier!
Toss in a 2lb bag of frozen cauliflower florets to a pot--no need to thaw. Add in a chopped onion, diced potatoes, a clove of garlic and 4 cups of chicken broth. Cover the pot and let it come to a boil, and then lower the heat to simmer for 20 minutes. Use an immersion blender to puree the vegetables. Add in a cup of whole milk, stir and taste. If needed, add a pinch of salt and pepper. That's it!
It's so easy, healthy, and great for these rainy indoor kind of days.
