Preheat oven to 400 degrees.
Make honey mustard sauce by whisking all of the ingredients together in a small bowl, set aside.
Slice dinner rolls in half and place just the bottoms, cut side up on a baking sheet covered in foil.
Add 1 teaspoon of the honey mustard sauce onto the top of each roll on the sheet. Place one slice of ham folded into a pile onto the top of each roll, directly on the honey mustard. Lay 1/2 a slice of Swiss cheese folded in half on top of each piece of ham.
Next, lay a slice of chicken breast, folded in a pile on top of the cheese. Then add the other half of the Swiss cheese on top of the chicken breast.
Place rolls tops back on, placing directly on top of the cheese and bake for 5-6 minutes.
And use the remaining honey mustard sauce for dipping.
Or you can, like I did, add the extra remaining honey mustard sauce onto the cut side of each roll, 1 teaspoon on each roll, then lay the rolls on top and place in the oven to bake for 5-6 minutes or until cheese is completely melted.
