METHOD:
First make the croutons: heat the oil in a large frying pan. Add the bread cubes and fry for 4-5 minutes over a medium heat stirring until the croutons are golden. Place in a large bowl.
Tear the lettuce into large pieces and add to the bowl. Drain the anchovies reserving 2 tbsp of the oil for the dressing. Dice the anchovies and add to the lettuce with the Parmesan cheese.
Place all the dressing ingredients and anchovy oil in a food processor and blend until smooth. Season to taste with salt and freshly ground black pepper.
Add the dressing to the salad bowl and toss until well coated. Serve immediately.
