Preheat your oven to 200°C (392°F).
Cut the chicken breast into bite-sized pieces.
Slice the leeks thinly and rinse them thoroughly.
In a large pan, cook the chicken pieces over medium heat until they are browned and cooked through.
Add the sliced leeks to the pan and cook until they are soft.
Stir in the dijon mustard, natural yoghurt, and chicken stock. Mix well and let it simmer for a few minutes.
Add the thyme and season with salt and pepper to taste.
Pour the chicken and leek mixture into a pie dish.
Roll out the puff pastry and place it over the top of the pie dish, trimming any excess.
Make a few small cuts in the pastry to allow steam to escape.
Bake in the preheated oven for 20-25 minutes, or until the pastry is golden brown.
Let the pie cool slightly before serving.
