Preheat the oven to 180/350/GM 4. Fry 1 leek (cleaned and sliced), and 1 clove garlic (peeled and crushed) in olive oil for 5 minutes. Transfer to a large saucepan. Use the frying pan to fry 1 kg of mushrooms (wiped and diced) in batches, for 5-7 minutes each batch. Transfer them to the large pan and add 1 tsp chopped thyme. Stir in 300ml of soya cream and 100g cashew nuts. Cook for 7-8 minutes, stirring. Remove from heat and season. Place in a pie dish and cover with ready-rolled puff pastry. Brush the top with a little soya milk and bake for 20-25 minutes. Serve with green vegetables such as purple sprouting broccoli or green beans.
