Put a pot with water on and add the two stockcubes. As soon as it boils add the chicken fillet and leave to simmer for about 10 minutes. Drain and leave to cool. As soon as it is cold enough you pull the chicken apart either with your hands or with a fork.
In the meantime you cook the pasta according to the instruction on the package and leave to cool. Cut the broccoli into small florets and briefly cook them for about 4 minutes in boiling water. Drain and rinse with cold water to stop the cooking process.
Combine penne, broccoli and the chicken in a large bowl. Add the tomatoes (either cut in half or in quarters)
Make the dressing by combining the ingredients and mix this with the salad. Sprinkle with fresh basil before serving
