Preheat your oven to 350° F. Using a medium-size mixing bowl, combine the turkey and the sausage and mix thoroughly.
Add the egg, oatmeal, and breadcrumbs and continue to mix. Stir in the barbecue sauce and remaining ingredients until everything is blended together.
Lightly oil a standard-size loaf pan. Place the meat mixture into the loaf pan and shape the top to conform with the contour of the pan. Next, pour an additional 1/2 cup barbecue sauce on top of meat and distribute evenly with spoon or spatula.
Bake uncovered for 40-45 minutes until meat is cooked throughout.
