Preheat your oven to 400°F (200°C).
In an 8-inch oven-safe skillet, combine the cherry tomatoes, chickpeas, and minced garlic.
Drizzle with olive oil and sprinkle with dried oregano, sea salt, and black pepper, tossing to coat the vegetables evenly.
Place the skillet in the oven and roast for 15 minutes until the tomato skins begin to blister and burst.
Remove the skillet from the oven and carefully pour the liquid egg whites over the roasted vegetable mixture.
Crack the three whole eggs into the skillet, spacing them out evenly so they do not touch.
Sprinkle the crumbled feta cheese over the top of the egg and vegetable mixture.
Return the skillet to the oven and bake for 8 to 10 minutes, or until the egg whites are fully opaque and set but the yolks remain soft.
Remove from the oven and serve immediately while warm.
