Preheat your oven to 375°F (190°C).
Dice the Yukon gold potato into small 1/2-inch cubes to ensure even cooking.
Heat the extra virgin olive oil in an 8-inch oven-safe skillet over medium heat.
Add the diced potatoes to the skillet and sauté for 8-10 minutes, stirring occasionally, until they are tender and golden-brown.
Stir in the diced onion, red bell pepper, and lean ham, cooking for an additional 3-4 minutes until the vegetables soften.
In a medium mixing bowl, whisk together the large eggs, egg whites, sea salt, black pepper, and garlic powder until well combined.
Pour the egg mixture over the potato and ham mixture in the skillet, tilting the pan to ensure the eggs reach all edges.
Sprinkle the shredded sharp cheddar cheese evenly over the top of the egg mixture.
Transfer the skillet to the preheated oven and bake for 12-15 minutes, or until the eggs are fully set and the cheese is melted and bubbly.
