Fry the onions and bacon until the onions are soft and the bacon cooked.
Add the pork mince and cooked until brown, chopping up any clumps along the way. Add some black pepper and the chilli powder whilst cooking.
Add the corn flour and mix through for 1 minute, then add the chicken stock. Add the chopped celery, carrots and sundried tomato paste and mix together. Bring to the boil and simmer for 15 - 20 minutes with the lid on.
Meanwhile, make the pastry and preheat the oven to 200°c/190°c Fan.
Put the flour in a bowl, add the chopped butter and rub in until it resembles breadcrumbs. Add the water and combine until it forms a dough. Roll out onto a floured surface about 1cm thick and place the oven proof-dish on top and cut around it. Brush the top of the pastry with the beaten egg.
Add the mixture to the dish and place the pastry on top. Make 2 slits in the middle of the pastry with a knife, so steam can get through whilst cooking. Bake in the oven for 30 minutes.
Serve with steamed vegetables. Enjoy!
