Add the mushrooms and the flour and fry for a few seconds, giving the sauce a stir every now and then. Pour the sauce in a bowl and stir in the stock. Season with salt, pepper and olive oil. Heat the sauce to the boiling point in the pan and stir in the spinach. Cover and simmer until the spinach is soft but crisp, stirring every now and then, for a further 30 seconds or so. (If you like a more substantial, slightly more bitter sauce, add the crushed chillies and red chilli pepper in the last five minutes of cooking.)
When ready to serve, serve the soup with the sauce – either spooned over the top or spooned over the bottom of a bowl. Garnish with the spinach and breadcrumbs and serve right away, or to go with a good vegetarian meal.
