Fry bacon/ham in a little oil, do not brown, remove from pan

Add onion to pan, fry gently until transparent, if using mushrooms add at this stage, return bacon to pan.

Add sufficient gravy to moisten, you don't want it too wet, combine and allow to cool.

Heat oven to 200C

Place flour, suet and salt & pepper in a bowl, add enough water to make a firm dough.

On a floured surface roll into a rectangle approximately 3/8 -1/4 inch thick

Spread cooled bacon mixture evenly over pastry leaving a half inch gap all round edge.

Cook in centre of oven for 45- 60minutes, until golden brown

Serve sliced with potatoes and vegetables of choice and lots of gravy

You can spread a thin coat of your favourite barbecue sauce on the pastry before adding the bacon mixture for added flavour.

You can use this pastry (without the pepper) to make a jam or syrup roly poly, roll out pastry as above, spread with jam, raspberry for preference, or syrup, roll and bake as above, serve with lashings of custard.
