Sunny vegetable patties

Method

1. For the pastry, put the flour, turmeric and a pinch of salt in a bowl and rub in the butter with your fingers. Add 4-5 tbsp cold water, mixing quickly with a knife until the pastry comes together. Roll into a ball, wrap in cling film and chill for 30 minutes. Preheat the oven to 200°C/fan180°C/gas 6.
2. Put the pepper, carrot and squash in a saucepan with a small amount of just-boiled water to cover. Cover and cook for 4 minutes. Drain, place in a bowl and mix with the remaining filling ingredients.
3. Cut the pastry into 4 equal-sized pieces. On a lightly floured surface, roll out the pastry pieces to make 4 large ovals (approx 15cm in diameter) with the thickness of a pound coin. Divide the filling among the patties, placing it on one long half of each oval, leaving 1cm around the edge. Brush the edges with water, fold the empty halves over and use a fork to crimp the patty edges together.
4. Prick the patties a couple of times with a fork, brush with the beaten egg and cook for 25 minutes until golden on the outside and cooked through.
