In a small bowl, thoroughly mix the ground turkey with the dried sage, garlic powder, onion powder, sea salt, and black pepper to create a clean sausage base.
Heat the ghee in a large non-stick skillet over medium-high heat until melted and shimmering.
Add the seasoned turkey to the skillet, breaking it apart with a spatula, and cook until browned and completely cooked through.
Add the diced red bell pepper to the skillet and sauté for 3-4 minutes until the pepper is tender and slightly caramelized.
In a separate bowl, whisk together the whole eggs and egg whites until the mixture is uniform and well combined.
Reduce the heat to medium, pour the egg mixture into the skillet, and add the baby spinach.
Gently fold the eggs and spinach into the turkey and pepper mixture until the eggs are softly scrambled and the spinach has wilted.
Sprinkle the shredded sharp cheddar cheese over the top, allowing it to melt for 30 seconds before transferring the mixture to a warm bowl.
