Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Dice the bell pepper, zucchini, and red onion into uniform bite-sized pieces.
Toss the vegetables on the baking sheet with the olive oil, sea salt, and black pepper until evenly coated.
Roast the vegetables for 15 to 20 minutes, or until they are tender and show slight caramelized edges.
While the vegetables roast, whisk the whole eggs and egg whites together in a medium bowl until the mixture is frothy and well combined.
Heat a large non-stick skillet over medium-low heat and add the grass-fed ghee, swirling to coat the pan.
Pour the egg mixture into the skillet and let it sit for 30 seconds before gently stirring with a silicone spatula.
Continue to cook the eggs slowly, using a folding motion to create large, soft curds.
When the eggs are nearly set but still moist, fold in the roasted vegetables and cook for an additional 30 seconds to incorporate.
Remove from heat, garnish with freshly minced chives, and serve immediately.
