In a bowl, combine the mayonnaise, cheeses, and shredded, skinless sausages, and mix well.

Add the oregano, mix everything well again, and set aside.

Cut a lid off the bread and remove the crumb, creating a cavity for filling. Use the crumb to make small squares of bread. Set aside.

Fill the bread with the prepared mixture.

Place the bread on a baking tray with the top and crumb side down, drizzle with olive oil, and bake at 200ºC for about 20 minutes or until the cheese is melted and a golden crust forms.
