- 2 cloves garlic, minced
- 1/2 pound (225g) sliced pepperoni
- 1/4 pound (115g) sliced salami

Instructions:
- Prepare the Dough: If making from scratch: Combine flour, yeast, and salt in a bowl. Add water and olive oil; mix until a dough forms. Knead for 5-7 minutes until smooth and elastic. Let rise in a greased bowl, covered, for 1-1.5 hours, or until doubled. If using store-bought: Thaw according to package directions.
- Sauté the Aromatics: Heat olive oil in a skillet over medium heat. Add onion and garlic; sauté until softened and fragrant. Remove from heat and let cool slightly.
- Assemble the Filling: In a bowl, combine the sautéed onion and garlic mixture, pepperoni, salami, ham, mozzarella cheese, Parmesan cheese, basil, oregano, and red pepper flakes (if using). Season with salt and pepper to taste.
- Roll Out the Dough: On a lightly floured surface, roll out the dough into a large rectangle, approximately 12x18 inches (30x45cm).
- Layer the Filling: Spread the filling evenly over the dough, leaving a 1-inch border along the edges.
- Roll Up the Stromboli: Starting from one of the long sides, tightly roll up the dough, jelly-roll style. Pinch the seam to seal tightly. Tuck in the ends and pinch to seal.
- Prepare for Baking: Place the Stromboli seam-side down on a baking sheet lined with parchment paper or a silicone mat.
- Score and Egg Wash: Using a sharp knife or pizza cutter, make several diagonal slits across the top of the Stromboli. Brush with the egg wash. Sprinkle with sesame or poppy seeds (optional).
- Bake: Bake in a preheated oven at 375°F (190°C) for 25-30 minutes, or until golden brown and the internal temperature reaches 165°F (74°C).
- Rest and Slice: Let the Stromboli rest for 10-15 minutes before slicing and serving.
