Preheat oven to 400°F and line a baking sheet with parchment paper.
Toss the chopped bell pepper, zucchini, and red onion with olive oil, sea salt, and black pepper.
Spread the vegetables in a single layer and roast for 18 minutes until tender and slightly browned.
In a medium bowl, whisk together the whole eggs and liquid egg whites until the mixture is uniform.
Heat a large non-stick skillet over medium-low heat and add the ghee to melt.
Pour the egg mixture into the skillet and let it sit for 30 seconds before gently pushing with a spatula.
Continue cooking slowly, folding the eggs until they are soft and creamy.
Fold the roasted vegetables into the eggs and remove from heat immediately.
Serve warm, garnished with fresh chives for a pop of color and flavor.
