Preheat oven to 350 degrees F. Spray a broiler pan with nonstick cooking spray and set it near your work area.
In a large bowl, whisk together eggs, bread crumbs, Parmesan, garlic, shallot, salt, pepper, oregano, and basil. Add beef and sausage and, using your hands, mix ingredients until just combined without overworking meat.
Use a 2-Tablespoon scoop to portion meat, placing a Mozzarella ball inside and rolling into a ball. Repeat with each portion, setting them on the roasting pan.
Wrap each meatball with a half slice of bacon, and secure with a toothpick. Place each on the broiler pan and bake 30-40 minutes, depending on how crispy you like your bacon.
While meatballs are baking, prepare your sauce. Combine balsamic and maple syrup in a small saucepan set over low heat. Bring to a simmer and allow to cook 3-4 minutes until sauce is reduced. Remove from heat and allow to cool.
Drizzle maple balsamic sauce over warm meatballs and serve immediately. Enjoy!
