Preheat your oven to 375°F and lightly grease a small oven-safe baking dish with a touch of olive oil.
Heat a skillet over medium heat with the olive oil and add the ground turkey, breaking it into small crumbles until browned.
Toss in the diced red bell pepper and sauté for 3 minutes until tender.
Add the baby spinach to the skillet, stirring just until the leaves wilt, then remove from heat.
In a mixing bowl, whisk the eggs and egg whites together with the sea salt, black pepper, garlic powder, and dried oregano.
Transfer the turkey and vegetable mixture into the baking dish, spreading it out into an even layer.
Pour the whisked egg mixture over the top, ensuring all the ingredients are submerged.
Bake for 20 to 22 minutes until the center is firm and the edges are slightly puffed and golden.
