Heat a skillet (Ø 10-inch) with olive oil. Add leek and sauté for 5 minutes. Season with a pinch of salt and pepper.
Mix eggs, sliced parmesan cheese, paprika, salt, and a pinch of pepper in a large bowl. Add it to the leek, cover with a lid, and let it cook over low to medium heat for 5-10 minutes until the eggs are set, and the parmesan cheese has been melted.
Sprinkle with parsley and chili pepper! Serve hot.
Notes
