Meatballs

1. To make the meatballs, place the oats in a blender. Blend on high for 2 minutes, until the oats form a flour. Set the oat flour aside.
2. Spray a large skillet with the olive oil spray and set the skillet over medium heat. Add the onion and celery. Cook the vegetables for 2 to 3 minutes, until the onion is translucent.
3. While the onion and celery cook, place the beef, oats, coconut milk, coconut aminos, nutmeg, salt, black pepper and 1 teaspoon of the parsley in a large bowl. Add the onion and celery to the beef mixture and mix the ingredients together with your hands. Roll the meat mixture into 16 ([q:1 1/2] inch) balls.
4. Place the skillet over medium heat. Add the meatballs to the skillet and cook them for 7 minutes. Gently flip them over and cook them for another 7 minutes. Once the meatballs have browned, transfer them to a plate. Set the plate aside.

Gravy

1. To make the gravy, add the cornstarch to the skillet and whisk it together with the leftover fat from the meat until the mixture is bubbly, 2 to 3 minutes. Add the broth, coconut milk, coconut aminos and mustard. Increase the heat to medium-high and simmer the gravy for 5 minutes to thicken it.
2. Add the meatballs to the skillet and sprinkle with the remaining 1 teaspoon of parsley. Serve the meatballs immediately topped with the gravy.
3. Store leftovers in the refrigerator for up to 5 days or in the freezer for up to 30 days.
