Add 1 tbsp olive oil to a frying pan. Add Quorn Swedish Style Meatballs and cook according to packet directions
In the meantime, start making the sauce. Add 3 tbsp butter to a heavy pan. When butter is melted, add 3 tbsp flour and cook for 1-2 mins until lightly browned.
Add beef-style stock slowly, stirring continuously until all incorporated. This will thicken slightly, so continue to stir for 1-2 mins, ensuring it is smooth. As the dish cooks, add extra stock to the sauce if it becomes too dry.
Add sour cream; soy sauce and mustard until combined.
Stir cooked meatballs into sauce mixture, and heat through.
Sprinkle chopped parsley on top, and serve immediately on its own or over pasta, rice, or potatoes!
