Nicoise Salad

1) For the vinaigrette, gently warm the vinegar, 50ml water, garlic and tarragon together in a pan

Remove from the heat and leave to infuse for 30 minutes

Strain into a bowl and whisk in the mustard

Slowly add the olive oil, whisking continuously

Set aside.<p>

2) For the salad, set a small pan of water on to boil and cook the eggs for 7 minutes until hard boiled

Cool.<p>

3) Place the potatoes in a pan, cover with water, season with salt and bring to the boil

Turn down the heat and gently simmer for about 10 to 15 minutes or until cooked

Refresh under cold water

When cold, slice into 1cm-thick pieces and place in a bowl.<p>

4) Bring a saucepan of water to the boil, season with salt and cook the French beans for 5 to 6 minutes

Remove and plunge straight into iced water

Drain and add to the potatoes.<p>

5) Add the tomatoes, olives, anchovies, onion, tuna and lettuce leaves

Dress the salad with about 5 tablespoons of vinaigrette and toss

Peel and quarter the eggs and place on top

Serve immediately.<p>

* Cook's Note: Whenever you make a salad, make sure that after washing the leaves or vegetables, you get rid of as much water as possible

Any remaining water will dilute the flavour of the vinaigrette.
