Cut the bread into medium sized cubes which should ideally be crouton sized.
Sprinkle 2 tbsp of olive oil over the bread and rub the oil into the bread. You can add a bit of salt if you prefer.
At a medium flame, cook the bread until they are crispy and brown. Alternatively, you can bake the bread for 8-10 minutes at 200C. Turn the croutons a few times while cooking.
Pour the remaining oil over the chicken breast.
Place a pan over medium heat for one minute and place the chicken into the pan. Cook each side of the chicken for 4 minutes. Check if the chicken is cooked by inserting the tip of a sharp knife into the thickest part of the chicken. The juice of the chicken should be clear with no sign of pink.
Peel the garlic and crush in a garlic crusher.
Mash the anchovies and mix with the garlic in a bowl. Add the rest of the dressing ingredients with a handful of grated cheese and mix well. The dressing should have the consistency of yogurt. If thicker, add few drops of water.
Cut large pieces of lettuce and place in a large bowl. Cut the chicken into medium sized strips and spread half of them over the leaves along with half of the fried bread. Add three-fourth of your dressing to the large bowl and toss well. Add the rest of the chicken and croutons and pour the remaining dressing on top.
Garnish with some Parmesan and serve
A tip for those looking to lessen the calories : Use Greek Yogurt instead of mayonaise.
