Dietary and accessibility notes: This soup can be made either vegan (no cheese) or vegetarian (with cheese garnish). It requires some chopping (especially of the fennel bulbs - you could substitute pre-chopped butternut squash, onions, and garlic), and an immersion blender, blender, or food processor for pureeing.

Edited to add: sid has suggested that this might also be good with goat cheese, a suggestion I can only agree with. If so, you may want to increase the salt a little.
