Ingredients
Method
1.Cut pastry in half and roll out one half to a rectangle 22cm x 30cm and the other half to 23cm x 31cm; an approximation will be fine. The thinner piece is the top of the pie. Put the bottom piece on a baking sheet lined with baking paper, cover with plastic wrap, put the thinner piece on top and refrigerate.
2.Put the mashed potato in a large bowl and season with salt and pepper. Add spring onions, capers, parsley and lemon zest. Mix well, then work in chopped broccoli or cauliflower. Add salmon, keeping it in large pieces, sprinkle with lemon juice, then add sour cream or crème fraîche.
3.Preheat oven to 200°C (fan-forced). Remove pastry from fridge. Lift off top piece of pastry leaving the bottom piece (the smaller piece) on tray. Dampen the edges with a little water. Spoon filling onto pastry, keeping it in from the edges. Nestle the eggs into filling, season with salt, and bury in tomatoes.
4.Loosely roll the top piece of pastry around a rolling pin and unroll it on top of the pie. Seal the pastry edges together, then crimp them, turning the edges of the pastry slightly inwards to ensure a good seal. Make 3 holes with a chopstick in the top of the pastry for steam to escape. Brush the top with extra virgin olive oil and sprinkle generously with sea salt, then prick with a fork.
5.Bake for 25 minutes, until puffed and golden. Serve hot or warm, sliced.
