Preheat the oven to 450 degrees F. Line a baking sheet with parchment paper or aluminum foil.
Gently combine the pork and turkey by hand in a large bowl. Stir together the oats, 2 tablespoons of the ketchup, 1/2 tablespoon of the mustard, the soy sauce, oregano, egg whites, onions, 1/2 teaspoon salt and 1 teaspoon pepper in a small bowl until combined. Add the oat mixture to the meat mixture and combine by hand until just incorporated.
Form the meatloaf mixture into 4 small football-shaped loaves, about 4 inches long and 1 1/2 inches thick, and place on the prepared pan. Stir together the remaining 2 tablespoons ketchup and 1/2 tablespoon mustard in a small bowl. Brush some of the ketchup mixture on each meatloaf.
Bake until fully cooked, about 20 minutes. Garnish with additional fresh oregano if desired, and serve.
