Preheat your oven to 375°F (190°C).
Peel and thinly slice the potatoes.
In a large oven-safe skillet, heat the olive oil over medium heat.
Add the sliced potatoes to the skillet and cook until they are tender and slightly golden, about 10 minutes.
In a large bowl, whisk together the eggs, salt, black pepper, and oregano.
Stir in the spinach and feta cheese into the egg mixture.
Pour the egg mixture over the cooked potatoes in the skillet.
Cook on the stovetop for about 5 minutes, until the edges start to set.
Transfer the skillet to the preheated oven and bake for 15-20 minutes, or until the frittata is fully set and slightly golden on top.
Remove from the oven and let it cool for a few minutes before slicing and serving.
