Combine the meatball ingredients in a large bowl and use a spoon to mix well. Mix in a little but of warm water if needed to help the meatball mixture stick together.
Once mixed, divide the meat mixture into 16 even sized balls, (about 2 tablespoons of meatball mixture) Meatballs should be about 2 inches.
Pan fry the meatballs 5-6 at a time in a large oven safe skillet or oven-safe fry pan with bacon grease. Browning them on all sides.
Once all have been browned, place the partially cooked meatballs into the skillet, and pour the marinara over the top.
Cut each slice of mozzarella into 4 even sized pieces, and gently place one over each meatball.
Bake uncovered at 350 degrees for 20-25 minutes until meatballs are cooked through and cheese is melted and golden.
Garnish with fresh parsley.
You can use all ground beef or any combination of the ground meats to achieve 1 ½ lbs.
You may or may not need water depending on the fat content of the ground meat you use. Use up to ⅓ cup of warm water in mixture to help mixture bind.
