Roast vegetable and houmous pie

Method

1. Preheat the oven to 220°C/fan 200°C/gas 7. Mix the onion, broccoli, peppers and courgettes in a roasting tin, tossing well with the cumin seeds and the oil. Roast for 30 minutes.
2. Remove and mix in the houmous, lemon zest and coriander. Turn the oven down to 200°C/fan180°C/gas 6. Cut the pastry in half to make 2 rectangles. Transfer 1 piece to a lined baking sheet and arrange the sweet potato slices in slightly overlapping layers to cover the pastry, leaving a 2cm border. Pile the roasted veg on top of the potatoes and brush the border with the egg glaze.
3. Roll the remaining pastry out a little thinner. Drape over the filling, press the pastry edges together to seal and trim away any excess pastry. Egg wash the top and cut 3 diagonal slits in the pastry.
4. Bake for 25-30 minutes, until the pastry is golden brown and puffed up. Serve with a dressed mixed salad.
