Preheat the oven to 170°C.

Lightly grease a baking tray. Layer the phyllo sheets one by one, brushing each sheet with olive oil.

In a bowl, combine yogurt, eggs, oregano, and crumbled feta. Mix until well blended. Season lightly with salt if needed.

Pour the mixture over the prepared phyllo base and spread evenly. Arrange the Florina pepper slices around the surface. Sprinkle with black pepper.

Fold the edges of the phyllo inward to create a rustic border and lightly brush with olive oil.

Bake for approximately 30 minutes, or until golden and set.
