Preparation
Bring a pan of water to the boil. When it comes to the boil, add the cod and simmer for about 10 minutes.
While you're waiting for the cod to be cooked, prepare the vegetables. Wash them very well. Remove the stalk from the leek and cut it into small pieces. As for the carrot, peel it, grate it into sticks and set aside.
Put the olive oil in a non-stick pan. Add the leek, season with salt, pepper and thyme, to taste. Add a little water and cook for about 15 minutes.
When the cod is cooked, drain the water and add it to the leek mixture.
In a bowl, beat the egg and white, previously separated from the yolk. Add and fold into the previously prepared mixture.
Sprinkle with the grated carrot, arrange the olives and serve.
