Add a drizzle of oil and, when hot, season the chicken breasts
and put them in the pan
Fry for 3-4 minutes each side until golden then transfer to the
oven for another 15 minutes or until fully cooked through
Whilst the chicken is cooking, toss the sliced bread with
another drizzle of olive oil in a large baking tray, then spread
out in a single layer alongside the pancetta slices & bake in
the oven until both the bread & pancetta is crisp &
golden
Remove and set aside
Meanwhile, make the dressing
Put the anchovies, garlic, egg yolks, lemon and mustard in a
pestle and mortar or small food processor & blend to a thick
paste. While blending, or with the motor running, slowly drizzle in
the olive oil, so the sauce thickens to the consistency of runny
mayonnaise. If it starts to look greasy at any point, add a splash
of warm water
Once you've added all the oil, stir through the grated
Parmesan, taste and season with extra lemon juice if required
To assemble, slice the chicken breasts. Arrange the lettuce
leaves between 4 serving bowls, then scatter with the croutons
& bacon. Use a vegetable peeler to shave Parmesan over the
top, then drizzle over half the dressing and top with the sliced
chicken. Drizzle over the remaining dressing
