1 medium ciabatta loaf (or 4 thick slices crusty white bread)
3 tbsp olive oil
2 skinless, boneless chicken breasts
1 large cos or romaine lettuce, leaves separated
For the dressing
1 garlic clove
2 anchovies from a tin
medium block parmesan or Grano Padano cheese for grating and shaving (you won’t use it all)
5 tbsp mayonnaise
1 tbsp white wine vinegar
1 Heat oven to 200C/fan 180C/gas 6. Tear 1 medium ciabatta into big, ragged croutons or, if you prefer, cut with a bread knife. Spread over a large baking sheet or tray and sprinkle over 2 tbsp olive oil.
2 Rub the oil into the bread and season with a little salt if you like (sea salt crystals are best for this). Bake for 8-10 mins, turning the croutons a few times during cooking so they brown evenly.
3 Rub 2 skinless, boneless chicken breasts with 1 tbsp olive oil, season. Place pan over a medium heat for 1 min, until hot, but not smoking. Lay the chicken on the pan (it will sizzle if it’s hot enough) and leave for 4 mins.
4 Turn the chicken, then cook for 4 mins more. Check if it’s cooked by poking the tip of a sharp knife into the thickest part; there should be no sign of pink and juices will run clear.
5 Bash 1 garlic clove with the flat of a knife and peel off the skin. Crush with a garlic crusher. Mash 2 anchovies with a fork against the side of a small bowl.
6 Grate a handful of parmesan cheese and mix with the garlic, anchovies, 5 tbsp mayonnaise and 1 tbsp white wine vinegar. Season to taste. It should be the consistency of yogurt – if yours is thicker, stir in a few tsps water to thin it.
