Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Toss the diced bell peppers and zucchini with olive oil, sea salt, black pepper, and garlic powder on the prepared baking sheet.
Roast the vegetables for 15-18 minutes until they are tender and slightly caramelized at the edges.
While the vegetables roast, whisk together the whole eggs and egg whites in a medium bowl until the mixture is uniform and frothy.
Heat the ghee in a large non-stick skillet over medium-low heat.
Pour the egg mixture into the skillet and let it sit for 30 seconds before gently stirring with a silicone spatula to create soft, large curds.
When the eggs are nearly set but still slightly moist, fold in the roasted vegetables and the parmesan cheese.
Continue to cook for another 30-60 seconds until the eggs are fully cooked through, then serve immediately.
