Method
- Preheat your oven to 200C/180C fan, or pizza oven to a medium high heat. Arrange the bread slices in a single layer and drizzle over the olive oil and rub it into the bread with your hands. Season generously with sea salt and black pepper. Bake for 5-7 minutes until golden and crisp.  
- To make the dressing, place the egg yolk, lemon juice, vinegar, Worcestershire sauce, anchovies and garlic in a small bowl and blitz with a stick blender. Gradually add the olive oil in a thin steady stream, blitzing until emulsified. Add a little water if needed to bring the mixture to a pouring consistency. 
- Place the lettuce, prawns, seaweed thins, and half the croutons in a large bowl and drizzle over the dressing and toss together, scatter over 3/4 of the parmesan and toss together again. Tip the mixture onto a serving dish and scatter over the reserved croutons and parmesan. Serve immediately.
