Chicken and leek stroganoff

Recipe (serves 2)
Fry 2 chicken breasts in a pan till golden. You could add some white wine- I tried white wine vinegar but the resulting flavour was a bit too tangy!
Prepare 1 leek by cutting into 3 lengthy chunks, then halving across the middle. Wash carefully, then add to the pan.
Put on 100g long grain rice to boil.
Prepare around 6 mushrooms, slicing them thinly. Add to the pan.
After another few minutes, add 2-3tbsp creme fraiche and stir in well. Add 1 tbsp lemon juice.
Use some herbs to add extra flavour, such as thyme and oregano. 1 tsp is enough.
Serve up with the rice once the stroganoff is heated through.
