At an angle, use a bread or tomato knife to cut the top off of the boule. Sort of how you would a pumpkin.

Use your hands to remove the insides of the boule. Save for another use like breadcrumbs.

Next layer; avocado slices, bacon, deli meat, cheese, tomato, salt and pepper and fresh basil leaves. Gently pressing down on each layer as you go, making sure each ingredient is tucked nicely inside the loaf.

Replace the top of the loaf and wrap tightly with plastic wrap. Refrigerate for at least an hour.

Cut into fourths before serving.
