In a medium bowl, mix turkey, onion, Bisquick, egg, ketchup, oregano, salt and pepper. Divide into five equal loaves and place each loaf into a non-stick mini loaf pan.
In a small cup, mix remaining 2 tbsp ketchup with worcestershire sauce and brush onto each loaf for glaze.
Bake uncovered for 30 minutes or until loaves are no longer pink in center (160º using meat thermometer).
