Method

1. Cook the rice according to packet instructions, drain and set aside. Meanwhile, put the stock into a pan and bring to a simmer, then add the chicken and poach for 15-20 minutes, until just cooked through. Drain and leave to cool. Cut into bite-size pieces.
2. Melt the butter in a saucepan. Add the onion and mushrooms and cook for 2-3 minutes, until just softened. Take off the heat and stir in the rice, chicken and parsley. Add the chopped egg and lemon zest and mix well.
3. Roll out the pastry to 30 x 35cm and put on a non-stick baking tray. Spoon the chicken and rice mix onto 1 half, leaving a border at the edge. Brush the edges with water. Fold the pastry over and seal the edges.
4. Open-freeze for 4 hours on the baking tray. Remove from the tray, wrap in cling film and freeze again.
