Stir together the ground chicken, parsley, egg, salt, and pepper in a big bowl. Throw in the cooled onion and garlic mixture and give everything a good mix.

Spread the chicken mixture onto parchment paper, flattening it into a rectangle about ¾ of an inch thick and as long as an 8-inch loaf pan.

Place the deli ham slices over the chicken layer, leaving an inch on each short end without anything on it. Lay down the Swiss cheese slices on top of the ham.

Mix together the butter, apple cider vinegar, Dijon mustard, and sugar substitute in a small bowl. Spread it evenly over the loaf.
