In a large mixing bowl, combine the ground beef with the chopped onion.
Add in beaten egg and the low carb breadcrumbs.
Add garlic powder, Italian seasoning, salt and pepper.
Add tomato paste.
Using your hands (with or without gloves) Mix all of the ingredients together until fully combined.
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 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.
Add each meatloaf to a loaf pan and spray with a non-stick spray. I like coconut oil spray.
Top each of the meatloaves with a ¼ cup of marinara sauce.
Bake for 30 minutes. Remove from oven, and top each one with half of the remaining 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 (the USDA has the minimum safe internal temperature for ground beef at 160 degrees Fahrenheit).
