Lidia travels to Sardegna, the second largest island in the Mediterranean known for its beautiful granite rocks. With the help of her two grandsons, Lidia shows us how to make a delicious baked Fregola Casserole prepared with handmade pasta pearls accompanied by a sauce of pancetta, onion, and plump cherry tomatoes. And who doesn't love a roast lobster - especially with Lidia's homemade breadcrumb topping?
