Preheat your oven to 400°F and line a baking sheet with parchment paper.
Toss the diced sweet potatoes with olive oil, sea salt, and black pepper on the prepared sheet.
Roast the sweet potatoes for 20-25 minutes, tossing halfway through, until they are golden and tender.
While the potatoes roast, heat a non-stick skillet over medium heat and add the ground turkey.
Cook the turkey until browned and fully cooked through, breaking it into small crumbles.
In a medium bowl, whisk together the whole eggs, liquid egg whites, and garlic powder.
Add the fresh spinach to the skillet with the turkey and sauté for 1 minute until just wilted.
Lower the heat to medium-low and pour the egg mixture into the skillet.
Gently stir the eggs with a spatula until they are set and fluffy, being careful not to overcook.
Serve the high-protein scramble immediately alongside the roasted sweet potatoes.
