Heat up coconut oil in a large cooking pot over medium heat.
Sauté the fennel for about 5-10 minutes, or until if softens.
Add the garlic and ginger. Cook for a further 3-4 more minutes, stirring continuously.
In a small bowl, mix the cornstarch into the vegetable broth.
Add the beets, vegetable broth with cornstarch, bay leaf and salt. Bring to boil, cover, and allow to simmer. Leave for about an hour, or until beets are tender.
Transfer mix to a blender or food processor. Blend until you achieve a soup-like consistency. Add more broth if you need to thin it out a bit more, or a little bit of cornstarch if you need it thicker.
Serve warm, and garnish with fennel fronds.
