Pork stroganoff

1) Heat oil and butter in a heavy frying pan and cook the onions and mushrooms over medium-low heat for 7-10 minutes. Remove and set aside.
2) Add the pork to the same pan and quickly fry over a high heat for 3-5 minutes.
3) Add brandy and continue cooking until alcohol burns off, beef stock, mustard, bay leaf, salt and pepper.
4) Scrape the bottom of the pan to release all the brown bits, they will add lots of flavour to the sauce.
5) Add the mushrooms and onions back in the pan and cook for 3 minutes until everything is heated through and bubbling.
6) Stir in sour cream and parsley and take off the heat.
