One of the great things about cauliflower is how well it takes on the
flavors of other ingredients. In this case, the more pungent goat cheese adds an interesting and delicious dimension to the finished result. If you want more robust flavors, roast the cauliflower and onion before blending.
The flavor will be more complex, but be aware the soup will take on
a darker brown color as a result.
This quick and versatile soup makes a nice, light appetizer or a filling lunch when paired with a crisp, green salad.
