Step 1

Place the cashews in a pan and cover with the Rude Health Oat Drink. Add the curry powder and a pinch of salt and gently simmer for 10 minutes – you just want to soften the cashews rather than reduce the liquid

Step 2

Strain the cashews, reserving the liquid. Place the cashews in a blender and blitz, slowly adding the reserved liquid until you have a nice creamy sauce. You may not need all the liquid, so pour in slowly until you have the right consistency

Step 3

Stir in the miso paste and a dash of white wine vinegar, then taste and season with salt and pepper

Step 4

Place a large pan over a high heat and add the leeks with a splash of oil and pinch of salt. Cook for about 5 minutes, stirring to avoid any burning. Once starting to soften, scrape the leeks into a large bowl

Step 5

Place the pan back over the heat and add the mushrooms with the thyme and a little more oil. Fry for 5 minutes until cooked through then add to the bowl with the leeks

Step 6

Preheat an oven to 180°C/gas mark Fold in the sauce then transfer the mixture to a pie dish. Cut out a pie lid from the puff pastry sheet to fit the size of the pie dish. Fork around the edge of the pastry for decoration then lay the pastry over the pie filling, tucking the pastry down the sides of the dish to get a good seal. Cut two small air holes in the top of the pie then brush with a little coconut oil. Place in the oven for 30–40 minutes until the pastry is nice and golden, then serve
