This tuna pie wraps a rich, paprika-scented tuna and pepper filling in a crisp homemade pastry crust. It is satisfying served warm for dinner and just as good cold for lunchboxes, picnics, or make-ahead meals.
Make the pastry. Add the flour and melted lard to a food processor and pulse until the mixture looks like fine breadcrumbs. Stir the salt into the boiling water, then pour it in gradually and pulse just until a smooth dough forms. Wrap the dough and chill for 1 hour. If making the pastry ahead, add the white wine vinegar with the water; the dough can then be refrigerated for up to 2 days.
Prepare the filling. Heat the sunflower oil in a large frying pan over medium heat. Add the onion, green pepper, and red pepper, then cook for 8-10 minutes, stirring occasionally, until the onion is soft and translucent and the peppers have softened.
Add the tuna. Drain one can of tuna, then add it to the pan along with the remaining tuna and the oil from the other cans. Stir in the paprika and a pinch of salt. Cook for 5 minutes, stirring often, until the filling is hot and well combined. Remove from the heat and let it cool slightly before assembling. The cooled filling can be refrigerated for up to 1 day.
Assemble and bake. Heat the oven to 200°C/180°C fan/gas 6. Divide the chilled pastry in half. On a lightly floured surface, roll each half into a 30 cm round, about 5 mm thick. Place one round on a parchment-lined baking tray, spoon the tuna filling into the center, and leave a border around the edge. Cover with the second pastry round, press and crimp the edges firmly to seal, then brush the top with beaten egg.
Bake on the middle shelf for 25-30 minutes, or until the pastry is golden and cooked through. Let the pie rest for a few minutes before slicing. Serve warm or cold. Refrigerate leftovers in an airtight container for up to 2 days.
Let the tuna filling cool before adding it to the pastry so the crust stays crisp and easy to handle. For a smokier flavor, use half regular paprika and half smoked paprika. If you do not eat lard, use cold butter or vegetable shortening, but the texture will be slightly different.
