Prepare the chicken of the woods by cutting it into small pieces or tearing it into strips. Unlike delicate mushrooms, it won’t absorb much water, so rinsing is fine.At the same time, dice the onion, crush the garlic, and slice the smoked ribs into bite-sized pieces.
Heat a large pot with a splash of olive oil. Add the onion and cook until soft and lightly golden. Stir in the chicken of the woods, garlic, and ribs, cooking for another minute or two to release their flavors.
Chop the rest of the vegetables. Potatoes and cauliflower can be left in larger cubes for a chunkier soup, while carrots and tomatoes are better cut smaller so they blend smoothly into the broth.
Tip all the vegetables into the pot and mix well so they coat in the flavors from the mushrooms and ribs.
Pour in just enough water to cover the ingredients. Season with salt, pepper, and marjoram, then tuck in a bay leaf for extra aroma.
Bring the soup to a boil, then lower the heat and let it simmer gently for about 40 minutes with the lid on. Give it a stir now and then. Once the carrots and parsley root are tender, add the beans and corn (unless you already used fresh corn earlier).
While the soup cooks, make the dumplings. Beat the eggs in a small bowl, then add the flour and a pinch of salt. Mix until combined — a fork works perfectly and saves extra dishes.
Keep the soup at a steady simmer and drop in small portions of dumpling batter (about a third of a teaspoon each). Let them cook for 2–3 minutes, or until they rise to the top.
Remove the bay leaf before serving. Finish with a sprinkle of fresh parsley, grab some bread, and enjoy a warming bowl of your delicious mushroom minestra soup!
