How to Make It
Preheat the oven to 375°. On a lightly floured surface, roll out one piece of the pizza dough to a 14-by-10-inch rectangle, about 1/4 inch thick. With a long side facing you, layer half each of the ham, provolone and soppressata across the bottom half of the dough, leaving a 1/2-inch border on the bottom. Arrange half of the mozzarella strips across the soppressata. Top with half each of the basil leaves, roasted red pepper strips and chopped peperoncini. Loosely roll the dough around the filling and pinch the seams together to seal. Fold in the sides. Transfer the stromboli to a lightly oiled baking sheet, seam side down. Repeat with the remaining dough and fillings and place the stromboli on a second lightly oiled baking sheet.
Brush the strombolis with the egg wash and sprinkle with the sesame seeds. Make five 1-inch diagonal slashes across the top of each stromboli to allow steam to escape. Bake the strombolis for about 40 minutes, until golden. Transfer to a rack and let cool for 20 minutes before slicing. Serve warm or at room temperature.
