2 tbsp olive oil
Knob of butter
1 large red onion, finely sliced
2 large leeks, finely sliced
8 good-quality sausages, skins split
2 tbsp chopped fresh flatleaf parsley
1 tbsp chopped fresh sage
Flour, for dusting
500g pack puff pastry
Milk, for glazing
1. Heat the oil and butter in a pan over a low heat. Add the onion and leeks and gently fry for 10-15 minutes until tender. Set aside to cool.
2. Remove the meat from the sausages and put in a bowl with the herbs. Mix well and shape into 4 balls.
3. Preheat the oven to 200°C/fan180°C/ gas 6. On a floured surface, roll out the pastry to a 32cm square, then cut into 4 equal pieces. Divide the onion mixture among the squares and top each with a sausagemeat ball. Flatten slightly, then fold the pastry corners up to enclose the filling. Brush with milk, then chill for 10 minutes.
4. Place on a baking sheet and cook for 25-30 minutes, until golden and the filling is cooked – the pastry will puff up so you can now see the filling. Serve with a fresh, crunchy salad.
- TO FREEZE: Open-freeze the uncooked parcels until solid, then wrap well in cling film and foil and freeze for up to 3 months. Cook from frozen, adding an extra 10-15 minutes’ cooking time.
