Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Dice the bell peppers and zucchini into half-inch pieces, then toss them on the baking sheet with olive oil, sea salt, and garlic powder.
Roast the vegetables for 15-20 minutes until they are tender and show slight caramelized edges.
While the vegetables roast, crack the whole eggs into a bowl, add the liquid egg whites, and whisk vigorously until the mixture is uniform and frothy.
Heat the ghee in a large non-stick skillet over medium-low heat until melted and shimmering.
Pour the egg mixture into the skillet and let it sit for 30 seconds before gently pushing the eggs across the pan with a silicone spatula to create soft curds.
Continue cooking slowly until the eggs are mostly set but still look moist, then fold in the roasted vegetables and black pepper.
Remove from heat immediately, garnish with freshly chopped chives, and serve warm.
