Preheat your oven to 375°F and lightly grease a small oven-safe baking dish.
In a skillet over medium heat, add the olive oil and ground turkey, breaking it apart with a spatula as it cooks.
Season the turkey with sea salt, black pepper, garlic powder, and dried oregano, cooking until no longer pink.
Stir in the diced red bell pepper and fresh spinach, sautéing for 2-3 minutes until the peppers soften and spinach wilts.
In a medium bowl, whisk together the whole eggs and egg whites until well combined and slightly frothy.
Transfer the cooked turkey and vegetable mixture into the prepared baking dish, spreading it out evenly.
Pour the egg mixture over the turkey and vegetables, ensuring everything is submerged.
Bake for 20-25 minutes or until the center is set and the top is lightly golden brown.
