Preheat the oven to 375°F. Grease a large baking sheet and set it aside.
On a lightly floured surface, roll out the bread dough into a 14x10 rectangle. Spread the Dijon mustard down the middle of the bread the long way, leaving about 1-inch on both ends. Top evenly with chicken, ham, and cheese. Roll up jelly-roll style from the long side and pinch seams to seal. Carefully transfer to the greased baking sheet, seam-side down, and tuck the ends under. Cover and let rise for about 15-20 minutes.
Bake in preheated oven for 25-30 minutes or until golden brown.
Remove from oven. Allow the bread to cool 5 minutes before slicing and serving!
Notes
You can use pizza dough in place of the bread dough if you prefer.
I don't use an egg wash for this recipe but you can if you want to. It will make your stromboli a nice and shiny golden brown color.
Not a fan of Swiss cheese? Provolone is good, as well as Parmesan. I imagine mozzarella would be tasty, too. Any Italian cheese!!
Dijon mustard is what makes this recipe for Chicken Cordon Bleu Stromboli, in my opinion. However, you can leave it out, and you don’t have to use it as a dipping sauce. Some folks in my family love Ranch dressing inside of the stromboli instead!!
