1 tbsp rapeseed oil
2 large onions , halved and thinly sliced
20g dried porcini mushrooms
3 tsp vegetable bouillon powder
300g chestnut mushrooms , chopped

300g potato , finely diced
2 tsp fresh thyme
4 carrots , finely diced
2 tbsp chopped parsley

STEP 1Heat the oil in a large pan. Tip in the onions and fry for 10 mins until golden. Meanwhile, pour 1.2 litres boiling water over the dried mushrooms and stir in the bouillon.
STEP 2Add the fresh mushrooms and garlic to the pan with the potatoes, thyme and carrots, and continue to fry until the mushrooms soften and start to brown.
STEP 3Pour in the dried mushrooms and stock, cover the pan and leave to simmer for 20 mins. Stir in the parsley and plenty of pepper. Ladle into bowls and serve each portion topped with 2 tbsp yogurt and a quarter of the walnuts. The rest can be chilled and reheated the next day.
