Preheat your oven to 375°F (190°C) and lightly grease a small oven-safe baking dish with a touch of olive oil.
Heat the olive oil in a skillet over medium heat and add the ground turkey, breaking it into small crumbles as it browns.
Add the diced red bell peppers to the skillet and sauté for 3-4 minutes until they begin to soften.
Stir in the baby spinach and cook just until the leaves are wilted, then remove the skillet from the heat.
In a medium mixing bowl, whisk together the large eggs, egg whites, sea salt, black pepper, garlic powder, and onion powder until well combined.
Transfer the cooked turkey and vegetable mixture into the prepared baking dish, spreading it out into an even layer.
Pour the egg mixture over the turkey and vegetables, ensuring everything is evenly submerged.
Place the dish in the oven and bake for 20-25 minutes, or until the eggs are fully set in the center and the edges are golden.
