Preheat your oven to 400°F (200°C).

Melt 2 tablespoons of butter in a skillet over medium heat. Add sliced mushrooms and season with salt and pepper; sauté for 5-7 minutes until tender. Stir in minced garlic and cook for an additional minute.

On a lightly floured surface, roll out your pizza dough into a rectangle, about 10x14 inches.

Layer provolone cheese, sautéed mushrooms, pepperoni, and mozzarella on the rolled dough, leaving a 1-inch border.

Roll the dough tightly from one long side to the opposite side, tuck the ends under to seal.

Transfer to a parchment-lined baking sheet. Whisk together olive oil, parmesan, and Italian seasoning; brush over the top.

Cut a few slits on the surface of the Stromboli and bake for about 25 minutes, or until golden brown.

Remove from the oven, let cool for 5-10 minutes, slice, and serve warm.
