Wash and air dry or pat dry the bell peppers. Cut the peppers in julienne strips.
Place skillet in medium heat and once hot, add olive oil. When oil starts to shimmer, add the peppers. Use the wooden spoon to flip them around as they cook. Try not to have the peppers overcrowd.
Stir slowly but constantly. Add sea salt, oregano and black pepper to peppers so they keep cooking while absorbing the flavors.
Once cooked thoroughly, add peppers to a platter. Crumble feta cheese and add on top of peppers. Serve some warm bread with peppers and the rest of the meal. Enjoy!
Notes
The way I season and cook these bell peppers is pretty minimalistic. But if you feel like adding onions, garlic, spicy seasonings or taco seasoning for example go ahead and try, there's nothing wrong with it! Oh they taste great with soy sauce too but they're no longer Mediterranean style if you add that.
