Veggie Shepherd's Pie

Meanwhile, halve, peel and thinly slice the onion. Thinly slice the chestnut mushrooms. Trim the carrot then grate on the coarse side of your grater (no need to peel).

Heat a drizzle of oil in a large frying pan on medium high heat. When hot, add the onion and mushrooms. Season with salt and pepper. Cook, stirring occasionally until soft and starting to brown, 7-8 mins. While the veggies cook, drain and rinse the chickpeas in a sieve. Grate the cheddar cheese.

Pour in the finely chopped tomatoes, water (see ingredients for amounts), the dried oregano and sun-dried tomato paste. Add the red wine stock pot and stir well to make sure it's dissolved. Stir in the grated carrot and the chickpeas then lower the heat until the mixture is simmering and cook with the lid off until the sauce is thick and tomatoey, 10-12 mins.

When the potato is ready, drain in a colander and return to the pan off the heat. Add a knob of butter (if you have any) and the hard Italian cheese and mash until smooth. Season with salt and pepper. Preheat your grill to its highest setting.
