Preheat your oven to 375°F (190°C) and lightly grease a small oven-safe baking dish.
Heat the olive oil in a non-stick skillet over medium heat. Add the ground turkey, breaking it up with a spatula, and cook until browned.
Stir in the diced onions and red bell peppers, sautéing for 3-4 minutes until the vegetables are tender-crisp.
Add the fresh baby spinach to the skillet and stir just until wilted, then remove the skillet from the heat.
In a medium bowl, whisk together the eggs, egg whites, sea salt, black pepper, garlic powder, and smoked paprika until well combined.
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 eggs are set in the center and the top is lightly golden.
Let the bake cool for 5 minutes before slicing and serving warm.
