Place parchment paper into a loaf pan or over a baking sheet, if you're forming your meatloaf without an loaf pan.
Place all of the ground turkey ingredients, from the ground turkey through to the thyme (not the glaze ingredients), into a large mixing bowl. With clean hands, mix the ingredients well, until fully blended.
Transfer the mixture to the loaf pan. If you're forming the loaf yourself onto a sheet pan, go ahead and do that now. Then, place the meatloaf in the fridge for at least 30 minutes to set.
Preheat oven to 350º F and position middle rack.
In a small bowl mix the ketchup and balsamic glaze. Then, spread it evenly over the top of the meatloaf.
Place the meatloaf in the oven and bake for about 40 minutes, or until the meatloaf reaches an internal temperature of 165º F.
Remove the meatloaf from the oven and let it sit for 5-10 minutes, to further set.
Garnish with chopped fresh parsley and serve.
