Combine warm water, yeast, and olive oil allowing to sit for 5 minutes until foamy. Gradually add flour and salt, mixing until a soft dough forms. Knead for 8-10 minutes until smooth.

Sauté diced bell peppers and cooked sausage or choice of vegetables in a skillet over medium heat for 5-7 minutes until softened. Remove from heat and stir in mozzarella cheese, olives, and Italian seasoning.

Preheat oven to 375°F (190°C) and line a baking sheet with parchment paper. Punch down the dough gently and roll it into a large rectangle, about ¼ inch thick.

Spread the filling evenly over the dough, leaving about an inch border. Roll the dough into a log shape and pinch the edges to seal.

Sprinkle the top of the rolled bread with garlic powder and grated Parmesan cheese. Add fresh parsley.

Bake for 25-30 minutes until golden brown and cheese is bubbly. Watch for aroma! A golden crust means it's ready.

Remove from the oven and cool for 5-10 minutes before slicing. This cooling period helps the filling settle.
