Put the dried shiitake into a jug and fill with 500ml of just boiled water, cover the jug with a lid and set it aside for 20 minutes (until the mushrooms have fully rehydrated)
Preheat oven to 180 °C Meanwhile, roughly chop your tempeh, red onion and red peppers into large chunks
Place the chopped tempeh into your food processor and blitz until it forms a chunky mince, decant it into a large oven tray
Continue this process with the onion and garlic, and then with the chopped red pepper and sundried tomato
Drain the shiitake water into a jug that contains the marmite and mix until it forms a stock. Blitz (or roughly chop) the drained shiitake mushrooms and mix them into the tray with the other ingredients
Stir the salt, oregano and spices, and the rapeseed oil into the tray and mix thoroughly
Place the tray into the preheated oven and cook for 30 minutes
Take the tray out of the oven and stir in the chopped tomatoes, the drained beans and the marmite stock
Place the tray back in the oven and cook for another 40 minutes, until it has a rich dark red colour to it, with a thick consistency
Stir in the cacao powder and serve!
