Remove the meat from the roast chicken and cut into bite-sized pieces. Roast the pine nuts without oil and cook the pasta until al dente according to the instructions on the packet. Mix a marinade of oil, lemon juice, salt, pepper and sugar.
Put the chicken, the lukewarm pasta, olives, pine nuts and the plucked basil leaves in a bowl and mix with the marinade. Let it steep a little, season to taste and, if necessary, add seasoning. Add the rocket just before serving.
Tip: If you like parmesan, you can slice some of it over it.
