Green Soup

5 cups beef or vegetable broth
1 cup chopped spinach
1/2 cup minced green onion
1/2 cup mixed greens (kale, beet tops, etc.)
1/4 cup chopped parsley
2 teaspoons each of Tarragon and Rosemary
1 tablespoon flour
6 tablespoons sour cream
4 hard-boiled eggs

Bring the broth slowly to a boil in a pot. Add the spinach, onions, mixed greens and herbs and simmer slowly for 1 hour. Remove the pot from heat. Mix the flour and sour cream to a smooth paste and whisk into the soup. Return to heat and stir until thickened and comes to a low boil. Add a little more sour cream and serve it with a hard-boiled egg in each bowl.
