1Soak the soya chunks in a bowl of water for 10-15 minutes. Then, squeeze out all the excess water using a cheesecloth or your hands.
2Heat 2-3 tbsp of oil in a pan, fry the onion until translucent. Then add 0.5 tsp turmeric and add the garlic. Fry for a couple of minutes until softened.
3Add the vegan mince or soya, bell pepper and mushrooms. Add in the salt and spices, lemon juice and tomato paste. Fry for 5 minutes.
4Add 2 cups of boiling water, place the lid on, then let it simmer on low heat until most of the water has evaporated.
5Bring a large pot of salted water to boil, add 0.5 tsp turmeric & cook the pasta until al dente. Drain in a colander.
6Brush 3 tbsp of oil to the bottom of a large non-stick pot.
7Mix the pasta and the sauce together, leaving aside a small amount of plain spaghetti. Place the plain pasta down. Then add the rest of the saucy pasta.
8Wrap the lid of the pot in a clean tea towel and tightly cover the pan. Set it at a medium heat for 5 minutes, then leave it to steam on a low heat for 45 mins-1 hour.
9To serve, place a large plate on top of the pot, hold the handles very tightly and flip the pot upside down.
