Steps:

• Mix the breadcrumbs, milk, parsley, egg, Worcestershire sauce, onion, chili powder and garlic in a large bowl. Add the meat, season with salt and pepper and mix with your hands until combined. Shape into six 3-to-4-inch oval loaves.
• Heat the vegetable oil in a large nonstick skillet over high heat. Add the loaves and brown about 3 minutes per side.
• Whisk the ketchup, sugar and vinegar in a bowl and brush a few tablespoonfuls over the meat. Add 1/2 cup water to the skillet, cover and simmer over low heat until cooked through, about 15 minutes.
• Transfer the loaves to a plate. Add the remaining ketchup mixture to the skillet and cook over high heat, stirring, until thick, 3 to 5 minutes. Serve 4 meatloaves with the hot glaze, reserving 2 for quesadillas.

Steps:

• 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.
