Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.

In a skillet over medium heat, cook ground meat until browned. Add peppers, onions, and mushrooms, cooking until softened. Season lightly and let cool slightly.

On a floured surface, roll pizza dough into a large rectangle.

Spread cooked filling evenly over the dough, leaving a border. Top generously with shredded cheese and pepperoni if using.

Starting from the long side, carefully roll into a tight log. Pinch seams and tuck ends underneath.

Transfer to baking sheet seam-side down. Brush with egg wash and sprinkle with seasoning.

Bake for 25–30 minutes until deeply golden and crisp. Let rest 5–10 minutes before slicing.
