Mushroom and chicken stroganoff

I had intended to make a mushroom stroganoff, but I had a load of cooked chicken left from Sunday roast so I threw that in too.

Ingredients (serves 2)

Small onion
150g mushrooms
165g cooked chicken
120ml half fat sour cream
300ml vegetable stock
1/2 tsp paprika
1/2 tsp chopped garlic
Salt/pepper

* chop the onion and mushroom and fry in a little oil for a couple of minutes
* add the sour cream and stock, paprika and garlic, and season well
* add the cooked chicken
* simmer for 20 minutes then serve with rice
