Here's how
1. Cook the linguine in a large saucepan of boiling water according to the packet instructions. Drain the pasta, reserving 1/2 cup water in case you need to thin the sauce.
2. Meanwhile, cut the smoked chicken breasts into thin slices.
3. Put the sour cream in a frying pan and warm it over a low heat until it thins. Do not boil or the sour cream will separate. Stir in the mustard and chicken and season with salt and freshly ground black pepper.
4. Toss the linguine into the sauce and mix well. Sprinkle with the parsley and serve immediately.

Tip: Smoked chicken is usually sold in the deli section at the supermarket. If smoked chicken is not available, use 3 chicken breast fillets, lightly fried in a little olive oil. Allow to cool slightly before slicing.
