Preheat your oven to 400°F (200°C).
Dice the zucchini and bell peppers into bite-sized pieces and thoroughly rinse the chickpeas.
On a parchment-lined baking sheet, toss the zucchini, peppers, and chickpeas with olive oil, sea salt, black pepper, and dried oregano.
Roast the vegetables for 15 minutes until they are tender and the chickpeas have a slight crunch.
Transfer the roasted vegetable mixture into a small oven-safe skillet or a 6-inch baking dish.
In a medium bowl, whisk the whole eggs and liquid egg whites together until well combined.
Pour the egg mixture over the roasted vegetables and sprinkle the crumbled feta cheese evenly across the top.
Return the dish to the oven and bake for 12 to 15 minutes, or until the eggs are fully set and the edges are lightly golden.
