Vegetarian paella

Heat a heavy-based frying pan, spray the surface with non-stick spray and add the peppers. Cook over a medium heat, turning occasionally, until lightly browned. Add a few drops of olive oil to ensure they do not stick. Cook for at least 20 minutes, turning occasionally, until completely soft.
Heat remaining oil in a large saucepan and add the rice and leeks. Stir-fry until the rice is glossy and the leeks are translucent.
Add the turmeric, garlic and mushrooms and continue to stir-fry until the mushrooms start to wilt.
Add the stock and carrots, cover and simmer for 20 minutes, or until the rice is cooked and the liquid has been absorbed.
Remove from the heat and allow to stand for 5 minutes. Stir in the cooked peppers, artichokes (or brussels sprouts – see tips) and tomatoes.
Season to taste with seasoning salt and freshly ground black pepper and stir in the basil and origanum, using a fork.
Transfer to a serving bowl and dot with cheese, olives and sprigs of herbs before serving.
