Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Toss the diced bell peppers, zucchini, and red onion with avocado oil, sea salt, and black pepper on the prepared baking sheet.
Roast the vegetables for 15-20 minutes, or until the edges are golden and caramelized, then remove from the oven.
In a medium bowl, whisk together the whole eggs, egg whites, and nutritional yeast until well combined and slightly 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 spatula to create soft curds.
When the eggs are nearly set but still moist, fold in the roasted vegetables and continue cooking for 1 minute.
Garnish with freshly chopped chives and serve immediately.
