Golden mixed greens pie

It might look like I live on sweets, but no – I eat savory food, too, and try to eat my greens as frequently as possible. :)
This tart is delicious and not difficult to make – you just need to plan accordingly so the dough has time to rise and the good thing is: you can make it in advance and reheat it before serving.

Golden mixed greens pie
slightly adapted from the absolutely gorgeous Home Baking: The Artful Mix of Flour and Traditions from Around the World

Dough:
1 teaspoon active dry yeast
2 tablespoons warm whole milk
1 cup (140g) all purpose flour
2 large eggs
1 tablespoon sugar
¾ teaspoon salt
1 tablespoon unsalted butter, softened
½ cup (60g) cake flour*
melted butter, for brushing

Filling:
1 large bunch dandelion greens or other bitter greens – I used escarole
1 large bunch spinach
½ tablespoon olive oil + more if necessary
1 garlic clove, minced
1 scallion, white and most of green parts, chopped
salt, to taste (about ¾ teaspoon)
1/8 teaspoon freshly ground nutmeg
1 ½ tablespoons pine nuts, lightly toasted and cooled

Dough: dissolve the yeast in the lukewarm milk and stir in 1 ½ tablespoons of the all purpose flour.
Break the eggs into the large bowl of an electric mixer (attached with the dough hook) and lightly whisk them with a fork. Add the yeast mixture and the remaining all purpose flour and mix on low speed until very smooth. Add the sugar, salt and butter and mix well. Add the cake flour and knead on low speed for 5 minutes or until smooth.
Transfer the dough to a lightly buttered large bowl, cover well with plastic and let rise until doubled, about 2 hours.
Meanwhile, make the filling: chop the greens into 2.5cm (1in) pieces, discarding any thick stems.
In a very large saucepan, heat the olive oil over medium heat. Add the garlic and scallions and cook for about 1 minute, until the scallions begin to soften. Raise the heat to high, add the chopped greens, salt and pepper and cook, stirring constantly, for about 1 minute or until greens are wilted (work in batches if necessary). Transfer the greens to a plate and let cool to room temperature. Taste for salt the stir through the nutmeg and pine nuts.
Preheat the oven to 230°C/450°F. Line a large baking sheet with foil then lightly brush the foil with oil.
Turn the dough onto a lightly floured surface and cut into 2 slightly unequal pieces: the larger one will be the bottom crust. Flatten the larger piece of dough onto an oval about 40x25cm (16x10in) and transfer onto the prepared sheet. Press the filling onto a colander, using your hands too, to extract the maximum water possible. Spread the filling over the dough leaving a generous 2.5cm (1in) rim all around uncovered. Roll the remaining piece of dough onto an oval about 37x20cm (15x8in). Place it over the filling and fold the edges of the bottom dough up over the edges of the top to seal the edges in the filling, then twist it, making a twisted rolled edge all round. Use a sharp knife to make slits in the top crust. Brush with the melted butter (I forgot to do that).
Bake the pie for 8 minutes, then lower the heat to 200°C/400°F and bake for another 8-10 minutes or until pie is deep, rich golden brown.
Transfer the pie to a wire rack and cool for 20 minutes.
Serve warm or at room temperature.
