Preheat your oven to 400°F and line a baking sheet with parchment paper.
Dice the russet potato into small, even cubes and toss them in a bowl with the olive oil, sea salt, and black pepper.
Spread the potatoes in a single layer on the baking sheet and roast for 20 to 25 minutes until they are tender and golden brown.
While the potatoes are roasting, place a non-stick skillet over medium heat and brown the ground turkey until it is fully cooked through.
In a separate bowl, whisk together the large eggs, liquid egg whites, and garlic powder until the mixture is well combined and frothy.
Add the fresh spinach to the skillet with the turkey and sauté for about one minute until the leaves are just wilted.
Reduce the heat to medium-low and pour the egg mixture into the skillet with the turkey and spinach.
Gently scramble the eggs with a spatula, moving them constantly until they are set but still moist.
Divide the roasted potatoes onto plates and top with the hearty egg and turkey scramble to serve.
