"A simple yet tasty alternative to potato leek soup. Great for those watching their carbs or calories, or just looking for a different vegetarian soup."
1Heat the olive oil and butter in a large pot over medium heat, and saute the leeks, cauliflower, and garlic for about 10 minutes. Stir in the vegetable broth, and bring the mixture to a boil. Reduce heat, cover, and simmer 45 minutes.
2Remove the soup from heat. Blend the soup with an immersion blender or hand mixer. Season with salt and pepper. Mix in the heavy cream, and continue blending until smooth.
