Preheat your oven to 375°F and lightly grease a small oven-safe baking dish.
Heat the olive oil in a skillet over medium heat and add the ground turkey.
Season the turkey with the sea salt, black pepper, garlic powder, onion powder, and dried oregano.
Sauté the turkey until browned and cooked through, breaking it into small crumbles with a spatula.
Add the diced red bell pepper to the skillet and cook for 3 minutes until slightly softened.
Stir in the baby spinach until just wilted, then remove the skillet from heat.
Transfer the turkey and vegetable mixture into the prepared baking dish, spreading it in an even layer.
In a medium bowl, whisk together the whole egg and egg whites until well combined.
Pour the egg mixture over the turkey and vegetables in the baking dish.
Top with the shredded sharp cheddar cheese and bake for 20 to 25 minutes until the eggs are set and the top is golden.
