Buy Seara Chicken Nugget. Seara Chicken Nugget is a sausage with a fine-ground chicken filling. It is one of the easiest foods in the world to eat because it is already cooked, and can be eaten straight from the package but should be cooked for at least 2-3 minutes more to release its flavours and taste. When it is brown or finished on the outside, it tastes better. It is a product that can be easily refrigerated and lasts for a long while. It has less oil content than regular sausages and is hygienically prepared. Seara Chicken Franks are soft, tender and ideal for quick and easy meals or for the barbecue.
