Roasted Cauliflower Soup

I got this recipe off Fat Free Vegan Kitchen, obviously not the prettiest meal, but it was so delicious. 
1 cauliflower
1 onion
2 cloves garlic, peeled
4 cups vegetable broth
1 large potato, peeled and cubed
1/4 tsp nutmeg
SI sea salt and pepper, to taste
4 drops truffle oil (optional)
smoked spanish paprika
Preheat oven to 400. Cut the cauliflower into florets and place them into a large baking dish sprayed with oil. Lightly spray the top of the cauliflower with oil. Bake for 20 minutes. Sprinkle the onion wedges and garlic on top of the cauliflower, spray lightly with olive oil, and return to the oven. Cook for 20-25 more minutes, stirring once halfway through.

While the vegetables are roasting, heat the vegetable broth and add the chopped potato. Bring to a boil and reduce the heat. Cook covered on very low until cauliflower is ready.

Add the cauliflower mixture to the broth. Puree it, in batches, in the blender until very smooth. Return it to the pot and add the nutmeg and salt and pepper to taste. Simmer for 10 minutes. Just before serving, stir in a few drops of truffle oil, if desired. Ladle into bowls and serve, sprinkled with smoked Spanish paprika.
