For a vegan version, omit the goat cheese or substitute with a plant-based alternative. If you don't have an immersion blender, you can carefully transfer the soup to a regular blender in batches and blend until smooth. Be sure to vent the blender lid to prevent pressure buildup. Feel free to add other vegetables to the soup, such as carrots, celery, or potatoes. Garnish with a dollop of sour cream, a sprinkle of red pepper flakes, or a drizzle of olive oil before serving.
