Preheat your oven to 375°F (190°C) and lightly grease a small oven-safe skillet or ceramic baking dish.
Finely dice the russet potato, red bell pepper, and yellow onion into small, uniform cubes to ensure even cooking.
Heat the olive oil in a skillet over medium heat; add the diced potatoes and cook for 5-7 minutes until they are tender and golden-brown.
Add the ground turkey, bell pepper, and onion to the skillet, sautéing until the turkey is fully cooked and the vegetables are fragrant.
In a medium bowl, whisk together the eggs, liquid egg whites, non-fat Greek yogurt, sea salt, and black pepper until the texture is silky and well-combined.
Transfer the turkey and potato hash into the prepared oven-safe dish, spreading it into an even layer across the bottom.
Pour the egg and yogurt mixture over the hash and bake for 15-20 minutes, or until the eggs are set and the edges are beautifully crisp.
