Melt the coconut oil in a thick-bottomed pan. Add the fennel, celery, onion, shiitake mushrooms, garlic and fennel seeds and sweat over a medium heat until they turn a light brown colour. Stirring continuously, add the thyme, bay leaves and beans and cover with the chicken broth. Simmer for 20 minutes. Remove the bay leaves and thyme and liquidize the soup, using a stick or jug blender, until smooth. Season with salt and pepper to taste and the lemon juice. Pass the soup through a fine sieve. Ladle into bowls and serve with the fried shiitake mushrooms.
