# List of Ingredients:

→ Dough and Base

01 - 1 loaf frozen white bread dough, fully thawed

→ Vegetable Filling

02 - 1 medium green bell pepper, diced
03 - 1 medium yellow onion, diced
04 - 1 cup mushrooms, thinly sliced

→ Meat and Cheese

05 - 3/4 pound deli roast beef, thinly sliced
06 - 8 slices provolone cheese

→ Spreads and Toppings

07 - 1/4 cup mayonnaise
08 - 1/2 teaspoon garlic powder
09 - 2 tablespoons unsalted butter, divided
10 - 1/4 teaspoon garlic salt
11 - 2 teaspoons sesame seeds
12 - 1 teaspoon dried parsley

→ Preparation

13 - Flour for dusting
14 - Nonstick cooking spray or parchment paper

# Preparation Steps:

01 - Place frozen white bread dough in a greased bowl, cover with plastic wrap, and let rise in a warm area until fully thawed and doubled in size. This typically takes 3 to 4 hours.
02 - Dice bell pepper and onion, and thinly slice mushrooms. Melt 1 tablespoon butter in a skillet over medium heat. Sauté the vegetables until softened and lightly browned, about 6 minutes. Let cool slightly.
03 - Heat oven to 375°F. Line a baking sheet with parchment paper or spray with nonstick cooking spray.
04 - On a lightly floured surface, roll the risen dough into a rectangle measuring approximately 12 x 18 inches, keeping the thickness as even as possible.
05 - In a small bowl, combine mayonnaise and garlic powder. Mix thoroughly then spread evenly over the surface of the dough, leaving a 1/2-inch border on all edges.
06 - Arrange roast beef slices evenly over the mayonnaise spread. Evenly scatter sautéed vegetables across the meat. Top with provolone slices, overlapping as needed.
07 - Starting at a long edge, roll the dough tightly into a log, keeping the filling secure. Pinch seam and ends to seal, then place seam-side down on prepared baking sheet.
08 - Melt remaining 1 tablespoon butter and brush it over the top of the roll. Sprinkle surface with garlic salt, sesame seeds, and dried parsley.
09 - Bake for 15 to 20 minutes or until the crust is golden brown and internal temperature reaches 165°F.
10 - Let stromboli rest for 5 minutes to allow the fillings to set. Slice with a serrated knife and serve warm.

# Additional Suggestions:

01 - Allow sautéed vegetables to cool before assembling to avoid soggy dough.
02 - Stromboli can be assembled ahead and refrigerated before baking; add a few extra minutes to the bake time if chilled.
03 - Substitute roast beef with cooked steak or ground beef; swap provolone for mozzarella or cheddar if preferred.
