Creamy cauliflower and tomato soup from Healy Real Food Vegetarian is an immune boosting dish. If you are fighting flu season or a cold, the ginger, garlic and lemon will help support your body's immune system. Cauliflower florets are sauteed with aromatics and herbs along with Brussel sprouts. When the vegetables become tender, roasted tomatoes are added to the pot. After an hour, the mixture is blended until smooth using a immersion blender. Milk is added at the end to make the soup extra creamy. Serve this cauliflower and tomato soup with a sprinkling of parmesan and a slice of sourdough bread.
