Flounder in Italian is very juicy, aromatic and tasty. Cooking such a fish is very simple and quick, use your favorite spices for cooking, and you can also pour a little lemon juice over the carcass. If you don’t have any cherry tomatoes on hand, then you can safely use ordinary ones. For this dish, you can take a whole carcass or ready-made fillet. Flounder is perfect for any side dish, as well as a festive table decoration.
