So easy that there's hardly a recipe to speak of. Don't worry about not having anything to flavour the water, congee can be made with nothing more than salt, and if you don't have a rice cooker with a congee setting, check out this simple stovetop recipe for the rice-water proportions you should use.
Your chances of finding a meat-free French onion soup at a restaurant are next to nil. But at home, a handful of dried porcini mushrooms steeped in hot water creates a full-flavoured broth that still lets the flavour of the onions shine through.
French onion soup doesn't call for much more than its star ingredient, and this simple (vegetarian) onion and fennel soup is delightful, if i do say so myself!
