Bring the water to the boil with the salt, pepper and the other ingredients for the court bouillon.
Let them infuse for 10 minutes before placing the fish in the court-bouillon.
When back at boiling point, cover with a lid and turn off the heat. The fish will cook through in the warm bouillon.
Prepare the dressing
Heat the canola oil and fry the bacon until crispy, then strain the oil, and allow it to cool.
Mix the Dijon mustard with salt, pepper and vinegar. Whisk in the bacon flavoured oil gradually. Season to taste.
Prepare the salad
Drain and rinse all the excess starch from the beans under cold running water.
Mix together with the remaining ingredients for the salad and keep cool.
Mix the dressing into the bean salad and remove the fish fillet from the court-bouillon just before serving.
