Green filo spiral pie

Preheat the oven to 190°C, gas mark 5 and place a baking sheet in to heat up. Butter then line the base of a 25cm loose-bottomed tart tin with baking parchment.

Warm the olive oil in a frying pan over a low heat, add the leeks and a pinch of salt then cook gently for about 10-15 minutes, or until starting to go translucent. Add the defrosted spinach and cook until as much moisture as possible has evaporated. Leave to cool.

Combine the cooked leeks and spinach in a bowl with the 2 whole eggs, cottage cheese, feta, pine nuts, nutmeg and herbs. Season with 1 tsp sea salt flakes and some black pepper. Mix well to combine.

Lay a sheet of filo out on a sheet of greaseproof paper, on a large work surface. Brush it all over with melted butter. Lay another sheet on top. Spread ¼ of the mixture all over the pastry as evenly as you can. It’ll be a little sparse, but don’t worry. Overfilling at this stage will lead to disaster.

Start by folding a 3cm border over, on both of the short ends. Standing with the rectangle of pastry landscape and longside towards you, fold up about 3cm of the bottom edge then carefully start rolling gently (more of a fold than a roll – you don’t want to squeeze the filling out). Once you’ve got all the way to the top, coil the sausage around the inside of the tin – start at the outside and work your way to the centre. Keep going, making more filo ‘sausages’ and continually coiling them into the centre. You want it nice and tightly packed in. If your packet of filo only has 7 sheets, just use a single layer on the last section. Brush the filo sheet with butter then add the filling and roll up as before.

Mix the remaining 1 tbsp melted butter with the egg yolk, then use to brush the top all over, as a glaze, and sprinkle with the sesame seeds. Bake on the preheated baking tray for 40 minutes, or until the pie is firm to touch, golden brown and risen. Leave to cool for a few inutes before serving, or leave to cool and freeze (in the tin, well wrapped) and defrost and heat through thoroughly when ready to serve.
