Preheat the oven to 200’C
Toss the sweet potato in the oil in an oven proof dish and bake for 20 minutes.
Add the pepper and bake for another 20 minutes
In the meantime, heat a splash of oil in a frying pan and fry the onions and chorizo for 5 minutes, or until crispy
Grease a pie dish with a little olive oil and spread out 4 or more of the sheets of pastry so they totally overlap and you have about 5 inches overlapping the edge.
Brush the pastry with some excess olive oil
Once the veg is cooked, stir in the pasatta, chorizo mix and goats cheese and pour into the pastry dish.
Fold the overlapping pastry over the top, along with and additional sheets so the filling is completely covered.
Brush with a little more oil.
Turn the oven down to 180’C and place the pie at the bottom of the oven to cook for 45-50minutes, until the top is lovely and golden.
Serve hot or cold with lots of salad
