Part 4/9:
Onions: One large diced onion sautéed in butter until lightly caramelized brings sweetness and depth of flavor.
Herbs and Spices: Dried oregano, paprika, black pepper, and fine sea salt are incorporated into the mixture, along with fresh chopped parsley, to give vivid, fresh flavor.
Egg: One egg binds the mixture together, ensuring it holds moisture and shape during cooking.
The onions are sautéed in butter for approximately 15 minutes until they develop a slight caramelization, adding richness to the filling.
