1Preheat your oven to 180°C (350°F).
Cut the top off the loaf of bread and hollow out the inside, leaving a shell about 1 inch thick.
In a skillet, heat the olive oil over medium heat. Add the chopped onion and cook until translucent.
Add the seasoned pork sausage to the skillet and cook until browned.
Stir in the diced tomatoes and dried oregano. Cook for another 5 minutes, allowing the flavors to meld.
Season the mixture with salt and pepper to taste.
Fill the hollowed-out bread with the sausage and tomato mixture.
Place the stuffed bread on a baking sheet and bake in the preheated oven for 15-20 minutes, or until the bread is crispy and the filling is heated through.
Remove from the oven, let it cool slightly, then slice and serve.
