Peel and dice the sweet potato into small 1/2-inch cubes.
Heat the extra virgin olive oil in a large non-stick skillet over medium heat.
Add the sweet potato cubes to the skillet and cook for 8-10 minutes, stirring occasionally, until they are tender and slightly caramelized.
Add the diced yellow onion and red bell pepper to the skillet, sautéing for an additional 3-4 minutes until the onions are translucent.
Push the vegetables to the side of the pan and add the ground turkey, breaking it up with a spatula.
Season the turkey and vegetables with sea salt, black pepper, garlic powder, and smoked paprika.
Cook the turkey until it is browned and cooked through, about 5-6 minutes.
In a small bowl, whisk together the whole egg and the egg whites.
Pour the egg mixture over the turkey and vegetables in the skillet.
Gently fold the eggs into the mixture, cooking until the eggs are just set and fluffy.
Toast the whole grain bread until golden brown.
Serve the scramble immediately alongside the warm toast.
