Peel the sweet potato and dice into small, uniform half-inch cubes to ensure even cooking.
Heat the ghee in a large non-stick skillet over medium-high heat until melted and shimmering.
Add the sweet potato cubes to the skillet and cook for 8-10 minutes, stirring occasionally, until they are tender and have developed a golden-brown crust.
Stir in the diced yellow onion and red bell pepper, sautéing for another 3-4 minutes until the vegetables are softened.
Add the ground beef to the pan, breaking it into small crumbles with a wooden spoon as it browns.
Season the mixture with sea salt, black pepper, garlic powder, and smoked paprika, stirring well to coat all ingredients.
Once the beef is fully cooked, pour the egg whites over the hash and stir constantly for 1-2 minutes until the whites are set and opaque.
Remove from heat and serve immediately while hot.
