Preheat your oven to 400°F and line a baking sheet with parchment paper.
In a mixing bowl, combine the lean ground turkey with the egg white, garlic powder, dried basil, salt, and pepper.
Divide the turkey mixture into two equal portions. Flatten each portion into a thin patty on a piece of parchment paper.
Place a slice of mozzarella (1 oz) in the center of one patty, then cover it with the second patty. Seal the edges well to encase the cheese fully.
Sprinkle the whole wheat breadcrumbs evenly over the surface of the formed patty to create a crispy exterior.
Place the stuffed turkey burger on the baking sheet and bake in the preheated oven for 20-25 minutes, or until the turkey is fully cooked and the exterior is golden and crispy.
While the burger bakes, lightly toast the whole wheat burger bun if desired.
Assemble your burger by placing the baked turkey patty in the bun. Optionally, add fresh greens or your favorite low-calorie condiment for extra flavor.
Serve warm and enjoy this delicious, balanced meal.
