There's pork pies but the hot water pastry is difficult to master...
Use Delia's recipe for the pastry - it really works well oh...you will need to use a bit more water than she recommends.
The filling - if folk object to offal modify the recipe to omit the kidney.
I augmented the filling recipe with finely chopped and fried open cup mushrooms and very finely chopped celery. I didn't bother with beef dripping and used olive oil.
You could research alternative fillings like
Savoury mince
Meat and potato
Meat and veg
Make sure that the fillings aren't runny when you make the pies as they can boil and bubble up through the upper crust's vents and spoil the presentation.
In summing up I'd say experiment with the fillings - you can rely on the crust recipe working if you take on board the need for a little more water.
Get the filling right - nothing too fancy, herby or spicy and you'll have a winner.
