Roasted cauliflower & Truffle soup I had to tweak the recipe a bit because it was really bland. Instead of super expensive truffle oil I just put dried Porcini mushrooms in a dish of olive oil and microwaved it for 30 seconds and drizzled that on top. Also added some of the Porcini mushrooms to the actual soup and parsley, oregano and garlic powder! DELISH!!!!!!!
