Preheat your oven to 375°F (190°C) and lightly grease an 8x8-inch baking dish with a splash of olive oil.

Heat the olive oil in a large skillet over medium heat, then add the sliced leeks and sauté for 10 to 12 minutes until they are soft, translucent, and slightly sweet, ensuring they do not brown too much.

In a medium bowl, whisk together the beaten eggs, Greek yogurt, crumbled feta cheese, and black pepper until well combined.

Stir the sautéed leeks directly into the egg and cheese mixture until they are thoroughly coated.

Transfer the mixture to the prepared baking dish, spreading it into an even layer with a spatula.

Sprinkle the yellow cornmeal and sweet paprika evenly over the top to create a rustic, crispy crust when baked.

Bake in the preheated oven for 30 to 35 minutes until the top is beautifully golden brown and the center is set.

Remove from the oven, let cool for 5 minutes to set, then garnish with fresh dill or parsley before slicing and serving.
