Preheat your oven to 375°F (190°C) and lightly grease a small oven-safe baking dish with the olive oil.
In a skillet over medium heat, cook the ground turkey until browned and fully cooked through, breaking it into small crumbles as it sears.
Add the diced red bell pepper to the skillet and sauté for 3 minutes until tender-crisp.
Stir in the fresh spinach and cook for 1 minute just until the leaves have wilted, then remove the skillet from the heat.
In a medium mixing bowl, whisk together the large eggs, egg whites, nutritional yeast, sea salt, black pepper, garlic powder, and onion powder until well combined.
Spread the cooked turkey and vegetable mixture evenly across the bottom of the prepared baking dish.
Pour the egg mixture over the turkey and vegetables, ensuring the liquid is distributed evenly.
Bake for 20 to 25 minutes, or until the eggs are completely set in the center and the top is slightly golden brown.
