For the soup, place all the ingredients in a blender and cover with the lid. Blend on high speed until smooth. Then gradually add water until the soup is of a drinkable consistency (about 500ml-750ml).
For the topping, heat the oil in a non-stick frying pan on a medium heat. Add the remaining ingredients and cook for 5 - 7 minutes or until the mushrooms begin to brown and pistachios are toasted, stirring occasionally as they cook.
Pour the soup into glass mugs and sprinkle with the topping to serve.
