Cook the pasta in a large pan of boiling water as directed on the packet. Five minutes before the end of the cooking time add the beans to the pasta. Drain when cooked.

Meanwhile, cut the chicken breasts into slices. Heat the oil in a large frying pan and add the chicken. Cook the chicken until it is browned and cooked through. Then stir in the lemon juice.

Add the stock and Philly. Heat gently until the Philly has melted and formed a sauce but do not boil.

Add the pasta and beans to the lemony chicken mixture and stir together. Serve immediately.
