In a large saucepan, sauté the salt, pepper, sage, ginger, onion and celery in olive oil until it begins to soften and caramelize.
Add 1 cup of the vegetable broth, the carrots and the squash, then simmer for 20-30 minutes.
Remove from heat and cool slightly.
Pour all of the contents into a food processor or blender. Add the remaining 3 cups of vegetable broth and puree everything together.
Return the puree to the saucepan. Add the heavy cream and simmer for an additional 10 minutes.
Serve hot and enjoy!
