This is a really easy soup for the cold days ahead.
3 or 4 medium size potatoes-peeled and cubed.
3-4 leeks chopped (use the white part until it turns green, discard of the dark green)
2 cups of mushrooms chopped (I used white button and shitake but you could use whatever you like/have)
1/2 white onion
3 tablespoons miso (or more depending on your taste)
Sautee the mushrooms and onion in olive oil for about 5 minutes, then add leeks and potatoes and sautee for about 10 minutes. Add miso, soya sauce, salt and pepper.
Stir until miso melts and then add enough water or veggie/chicken stock to cover the ingredients by an inch of liquid.
Bring it to a boil and then turn down to medium heat for 20 minutes.
Give it a chance to cool and then puree either with a hand blender or in a blender.
garnish with fresh rosemary or lemon juice.
