Steam cauliflower until soft, about 10 minutes. Pierce it with a fork to know that it's tender enough.
Heat a non-stick skillet on high, then place chopped sweet onion and cook for about 10 minutes, or until they begin to brown. No need to add any liquid for this, just be careful not to burn the skillet like I always do ;)
Add the cauliflower, onions, coconut butter, salt, turmeric, black pepper and vegetable broth to a high speed blender, and blend until completely smooth. You can leave some onions to place on top for garnish.
