Is Cauliflower Good for You?
Is cauliflower good for you? That would be a resounding yes.
Cauliflower, a cruciferous vegetable, contains unique plant compounds that are helpful in preventing cancer and heart disease. It’s also low carb and full of healthy fiber.
Cauliflower Rice anyone?!

I’m trying to avoid running to the store today & have all the ingredients other than olive oil. I do, however have some coconut oil hanging out in my pantry. Do you think it would work in this soup?
Michelle Perkins says
I made this recipe twice and found it a little bland, so I took the suggestions of some of the other commenters and added the chive oil and roasted garlic – YUM! Makes a huge difference, this is one of our staples now.
Rachel M says

I love cauliflower smashed with garlic. I cannot wait to try your soup!
Jan says
This was delish. I had a lot of organic garlic and a few bulbs of celeriac. So I roasted a head of garlic, too, and sautéed celeriac with the onions. I blended it all in a pot with a blending stick. It’s just great.
Jan says
Comment: I just saw Beth’s comment and my soup looked a lot like hers. I loved her call to add red pepper flakes.
Beth @ Tasty Yummies says
Thanks Jan! I always love an excuse to add those delicious red pepper flakes! One of my favorite things in my spice rack :)
