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 14×10 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 for 5 minutes before slicing and serving.
