Step 1

Preheat oven to 170°C.

Step 2

Place bread slices on a large baking tray, brush with oil. Place the bacon on a separate tray. Bake for 10-15 minutes until bread is golden brown and bacon is crisp.

Step 3

Remove both trays from the oven and set aside the bacon. While the bread is still warm, rub with a peeled and cut clove of garlic. Place in a small serving bowl and set aside. Break the cooled bacon into pieces and place in a small serving bowl.

Step 4

Grate 25g of parmesan and place in a food processor with mayonnaise, sour cream, remaining garlic clove, mustard and anchovies. Process to form a smooth dressing. Add 1-2 tablespoons warm water if the dressing is too thick. Pour into a serving bowl and set aside.

Step 5

Use a vegetable peeler to shave small pieces from the remaining parmesan and transfer to a small serving bowl. Place the lettuce leaves in a medium serving bowl.

Step 6

Arrange all the bowls on a large plate or platter so that the guests can help themselves.
