Preheat a non-stick skillet over medium heat and add the olive oil.
In a bowl, combine the lean ground turkey, egg white, minced garlic, dried oregano, chopped fresh basil, salt, and pepper. Mix until well blended.
Form the mixture into small, uniform meatballs.
Place the meatballs in the skillet and cook on all sides until browned and cooked through, approximately 8-10 minutes.
While the meatballs cook, prepare the whole wheat spaghetti according to package instructions until al dente.
In a separate saucepan, warm the marinara sauce over low heat.
Drain the spaghetti and toss with the marinara sauce.
Plate the spaghetti, top with the turkey meatballs, and garnish with additional basil if desired.
Serve warm and enjoy your balanced, hearty meal.
