Cut the onions into small cubes and the sun-dried tomatoes into small pieces. Remove the stalks from the rocket.
Roast the pine nuts in a pan without oil. Cook the penne al dente according to the instructions on the packet.
Cut the chicken breasts into strips. Heat 4 tablespoons of olive oil in a pan and fry the strips of meat. Season with pepper, salt and chilli (heat to taste). Add onions, tomatoes and garlic and continue frying everything on a small pan until the onions are translucent. Finally add the rocket. Fold in the penne immediately so that the rocket does not become too withered. Drizzle with chilli oil / olive oil if necessary.
Spread on pasta plates, sprinkle with parmesan to taste.
