Heat vegetable oil in a large frying pan and brown the beef, then set aside
Brown the kidneys in the same pan, add the onions and cook 3-4 minutes
Return the beef to the pan, sprinkle the flour over and coat the meat and onions
Add the beef stock, stir and bring to the boil
Reduce heat and simmer uncovered for 1½ hours, adding more beef stock if necessary
Remove from the heat, add salt, pepper and Worcestershire sauce and allow to cool completely
Place the cooked meat mixture into a pie dish
Roll out the puff pastry to 5mm thickness and 5cm larger than the dish
Lift the pastry over the pie dish, trim and crimp the edges
Brush the surface with the beaten egg mixture and bake 30-40 minutes until golden and puffed
