Oreganata is a classic Italian dish. Oreganata style refers to a mixture of breadcrumbs, olive oil, garlic, and oregano (hence the name "oreganata"). Lemon and parmesan cheese are often added as well in some recipes. The breadcrumb mixture is used to top seafood like fish, shrimp, and clams and then the dish is baked in the oven until the topping is crispy and golden brown.
