Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Dice the zucchini, red bell pepper, and red onion into small, uniform pieces.
Toss the vegetables on the baking sheet with the extra virgin olive oil, sea salt, and black pepper.
Roast the vegetables for 15 to 20 minutes until they are tender and show light golden-brown charred edges.
In a medium bowl, whisk together the whole eggs and liquid egg whites until the mixture is uniform and slightly frothy.
Heat the ghee in a non-stick skillet over medium-low heat until melted.
Pour the egg mixture into the skillet and let it sit for 30 seconds before gently stirring with a spatula to create soft, creamy curds.
When the eggs are nearly set, fold in the roasted vegetables and the crumbled feta cheese.
Cook for another 30 seconds until the cheese is just warm and the eggs are cooked through but still moist.
Transfer to a plate and garnish with freshly chopped chives before serving.
