Hydrate dried mushrooms around 15 min (in hot water).
Heat water for soup. Add veggies (personal choice) and chopped onions.
After 10 minutes add Rice Noodles (Optional).
Wait 5 minutes more and add hydrated dried mushrooms together with the liquid.
Add a bit of the porcini powder for more intense flavour, salt and pepper, and cook for another 5 minutes.
Add finely fresh parsley.
Bon Appetit!
P.S. Always wash dried mushrooms before soaking into water. This way we can use the yummy liquid in which mushrooms are hydrated.
