Pop the pasta to cook in salted boiling water for 8-10 mins.
Sauté the bacon in a little spray, on a medium heat till crispy. Remove and set aside.
In the same frying pan, sauté the chicken till just cooked, then throw over the Cajun spice and garlic and stir. Stir in the soft cheese and natural yogurt and season. Add a small ladle full of pasta water and stir in the herbs and lemon juice.
Simmer for a minute or so. Drain the pasta, add it to the pan, and pour over the chicken and sauce. Serve sprinkled with bacon and Parmesan. Lush.
