Preheat the oven to 350 degrees.

In a large mixing bowl, combine the 2 pounds of ground beef with one small chopped onion.

Add in a beaten egg and a ⅓ of a cup of pork rinds that have been made into very fine crumbs. You can break up the pork rinds by placing them in a Ziploc bag, and using a rolling pin to crush them into crumbs.

Mix in 1 teaspoon of garlic powder and 1 teaspoon of Italian seasoning, plus salt and pepper to taste.

Place 3 tablespoons of tomato paste into the bowl, and mix the ingredients together well. You will get the best results by mixing with your hands.

Form the meat mixture into two smaller oval shaped loaves. This will help them cook more quickly and evenly.

Make a divet down the center of each oval loaf of meat. Place a ½ cup of mozzarella cheese into the center of each meatloaf, and close the extra meat up over it, so that the cheese is stuffed into the center of the loaves.

Top the meatloaves with a ¼ of a cup of low carb marinara sauce.

Bake the meatloaves in a casserole dish for 30 minutes. Remove the meatloaves, and top with ¼ cup of shredded mozzarella cheese. Return them to the oven and cook for an additional 5-10 minutes until the cheese is bubbly and the meat is cooked through.
