Tips & Substitutions

For a creamier texture, consider adding a dollop of sour cream or Greek yogurt to the tuna mixture. If you don’t have mozzarella cheese, feel free to substitute with cheddar or a blend of your favorite cheeses. Using day-old bread can help absorb the milk mixture better, enhancing the dish's flavor and texture.
