This is a beautiful, simple avocado soup that is gluten and dairy free. The avocados are blended with sparkling water, lime juice and extra-virgin olive oil. The soup is then chilled. Although avocados are calorically dense they are a great source of healthy fats, fiber and potassium. Hass avocados have a higher percentage of oil than other varieties, making the texture more creamy. If you want to jazz up your soup, you can add toasted pumpkin seeds, additional red pepper flakes and a variety of fresh herbs.
