In a large bowl, combine the ground beef, bread crumbs, marinara sauce, parmesan cheese, parsley, and eggs.
Form the mixture into 8 round loaves and flatten each loaf slightly. Place loaves on a baking sheet and smoke for 25 minutes.
While the mini meatloaves are smoking, mix all of the glaze ingredients together in a small bowl.
Take the meatloaves out of the smoker and spoon 1-2 tablespoons of glaze over each loaf. Cook for another 10-12 minutes, or until the internal temperature reaches 165°F.
Garnish the finished meatloaves with freshly chopped parsley if desired and serve immediately.
