Instructions: 1. Slice the bread in half lengthways and scoop out the insides.

2. Chop the tomatoes and mix together with the breadcrumbs, olives and the herbs. Season and add enough oil to make the mixture into a paste.

3. Slice the avocado and the cheese and layer it alternately with the bread paste inside the bread.

4. When this process is completed place the top layer of bread and put the loaf between the chopping boards and place something heavy on top and leave overnight.

5. Remove the boards and slice the loaf to reveal the layers of colour.

6. Make the pesto mayonnaise by blending the sauce with the mayonnaise and water.

7. Serve a slice per person with a dollop of mayonnaise.
