Let's cook.
In a medium bowl, whisk together the eggs, Greek yogurt, dried oregano, and black pepper until well combined and slightly frothy.
Heat the olive oil in a non-stick skillet over medium heat until shimmering.
Pour the egg mixture into the hot skillet. Let it cook undisturbed for about 30 seconds, allowing the edges to set.
Using a spatula, gently push the cooked egg from the edges towards the center, tilting the pan to allow uncooked egg to flow underneath.
Continue cooking and gently folding the eggs for 2-3 minutes, or until they are mostly set but still slightly moist.
Sprinkle the crumbled feta cheese over the eggs and gently fold it in for another 30 seconds, until the feta is warmed through.
Remove from heat and serve immediately.
