This variation of Sarde a Beccafico includes a tomato sauce that adds a tangy and savory flavor to the dish. The sardines are stuffed with the traditional breadcrumb mixture and then baked in the oven. Meanwhile, a simple tomato sauce is made with fresh tomatoes, garlic, and olive oil. Once the sardines are cooked, they are served with the tomato sauce on top. The combination of the sweet stuffing and the tangy tomato sauce makes for a delicious and well-rounded dish.
