Preheat your oven to 400°F (200°C).
In a small oven-safe skillet or ceramic baking dish, toss the cherry tomatoes with extra virgin olive oil, sea salt, black pepper, and dried oregano.
Place the skillet in the oven and roast for 10-12 minutes until the tomato skins begin to blister and burst.
While the tomatoes roast, brown the ground turkey in a separate non-stick pan over medium heat until fully cooked, breaking it into small crumbles.
Remove the skillet from the oven and stir in the cooked turkey and fresh spinach, allowing the residual heat to wilt the greens.
Pour the liquid egg whites evenly over the tomato and turkey mixture.
Carefully crack the 3 whole eggs on top, spacing them out so they sit on the surface.
Sprinkle the crumbled feta cheese over the entire dish.
Return the skillet to the oven and bake for 8 to 10 minutes, or until the egg whites are fully set but the yolks remain soft and jammy.
Let cool for 2 minutes before serving directly from the skillet.
