For 4 people you will need:

500g of large dice chicken breast or thigh
1 large leek, washed, sliced thinly and drained
Pepper
Olive Oil

Sauce

2 tablespoons of Dijon Mustard
1 cup of chicken stock (or half and half with white wine)
2 tablespoons of chopped Coriander
1 tablespoon of Honey
½ cup of Yoghurt

Pasta

Pasta of choice such as Penne or Spirals (2 cups or so)
½ Cauliflower broken into small florets

Heat the olive oil in a fry pan and add the sliced leek; sauté until softened then add the chicken pieces and stir well and continue to sauce gently.

Make the sauce by mixing all the ingredients except the yoghurt.

Cook the pasta according to instructions. Add the cauliflower to the pasta cooking pot so that pasta is cooked and cauliflower is al dente.

Add the cooking sauce to the chicken, reserving about ¼ cup for the pasta
Coat the chicken and leek with the sauce and continue to simmer for about 15 minutes as the pasta is cooking.

To Serve:

Drain the pasta a cauliflower and coat with the reserved sauce
Add the yoghurt to the chicken pan and simmer to thicken ( if you want it as a really thick sauce add a little cornflour mixed with a little water)

Place pasta on plate (sprinkle with parmesan as an option and place chicken and sauce on top)
