2) Add stock and spinach with all of the dried herbs. Season with salt and fresh ground pepper to taste. Bring soup to a boil. Reduce heat to simmer soup for 20-30 minutes for flavors to meld. Remove from heat and let cool for 10 minutes.

3) In a heat-safe blender, blend batches of warm soup until smooth. Return smooth soup to soup pot and warm over low heat. Stir in half and half. Garnish with caramelized fennel, fennel fronds, a drizzle of heavy cream, or chopped parsley and basil. Enjoy warm with crusty bread.
