Preheat oven to 400°F and line a 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 olive oil, sea salt, black pepper, and dried oregano.
Roast for 15-20 minutes until the vegetables are tender and slightly browned.
In a medium bowl, whisk the whole eggs and egg whites together until the mixture is uniform.
Heat a large non-stick skillet over medium-low heat.
Pour the egg mixture into the skillet and cook, stirring gently with a spatula to create soft curds.
When the eggs are nearly set, stir in the roasted vegetables.
Remove from heat immediately and serve while the eggs are still tender and moist.
