Place all ingredients (except the marinara sauce and parmegiano reggiano cheese) into a large bowl. Mix thoroughly with your hands until all of the ingredients are well combined.
Place the meatloaf mixture into a loaf pan, gently pushing down until the top is flat.
Spread one cup of the marinara sauce evenly on the top of the meatloaf. Sprinkle the cheese on top.
Place in the oven and cook for one hour. When done, remove the meatloaf. You'll notice juice has pooled along the sides of the pan. Simply tilt the meatloaf while still in the loaf pan to drain the juice before serving.
