Method
Chop the meat into small dice. Heat the oil in a large saucepan or flameproof casserole dish. Add the onion, carrots and celery, then fry them gently on a medium heat for up to 10 minutes, until softening and just starting to colour.
Turn up the heat, add the meat and cook on a medium heat for a few minutes. Keep the stirring to a minimum until the underside is well browned, then stir until well coloured. Add the garlic and herbs and season.
Pour in the wine, let it bubble until reduced almost completely, then add the tomato purée or ketchup, gravy or stock and the Worcestershire sauce. Bring to the boil, then reduce heat and simmer for about 20 minutes. If the mixture looks in danger of drying out, add a little more stock or water.

Bring to the boil, then reduce heat slightly and simmer for about 20 minutes. When the potatoes are tender, drain and tip them back into the pan, then season with salt and add the butter.
Mash until smooth, adding a very little milk if they appear dry – they shouldn’t be. Pour the filling into an ovenproof dish (about 30cm x 20cm x 5cm/12in x 8in x 2in).
Using a spatula, spread the potatoes over the top as evenly as possible, then rough up the surface with a fork. Dot with butter. Put the dish on a baking tray and bake the pie in the oven for 25-30 minutes until piping hot inside and browned on top. Serve with green veg.
