400g Sirloin steak, cut into strips
1 Onion, sliced
400g Mushrooms, sliced
1tsp Wholegrain mustard
4tbsp Creme fraiche
In a pan on a low heat, gently sweat the onions and mushrooms in a bit of olive oil for 15 minutes, until soft. Transfer to a plate.
Turn the heat up (adding a bit more olive oil if necessary) and sear the sirloin strips. Add the paprika and wholegrain mustard.
Return the onions and mushrooms to the pan, also adding the creme fraiche, stirring until everything is mixed well. Continue to simmer for 5 minutes and season to taste. Serve with rice.
For an extra flavour add a splash of sherry or brandy when searing the meat and ensure the alcohol is burnt off before adding the onions and mushrooms.
