Preheat oven to 375 degrees.

In a bowl, mix the ground beef, egg, parmesan, pork rinds, 1/4 tsp salt, 1/4 tsp pepper, 1/4 tsp onion powder, 1/4 tsp garlic powder.

Spread this meat mixture onto a baking sheet. Make a 10 by 12 inch rectangle and about 1/2 inch in thickness.

Evenly spread out the spinach onto the meat. Sprinkle the remaining 1/4 teaspoons of salt, pepper, garlic and onion powders over the spinach.

Sprinkle the mozzarella over the spinach.

Roll up the meatloaf using the parchment to help you roll it over.

Bake for 40-45 minutes.

Allow to rest about 10 minutes before slicing.
