The egg is an essential ingredient in empanadas, acting as a binder to help them keep their shape and stay together when cooked. However, when it comes to hamburgers, breadcrumbs are not necessary. The chopped onion and herbs provide plenty of flavor, so there is no need to add breadcrumbs. But, if you're looking for a crunchy texture, adding some breadcrumbs to the meat mixture can be a great way to achieve that.
If you're using fresh meat, adding an absorbent ingredient such as breadcrumbs or even shredded bread from the pantry can help the hamburger stay together. This is especially important if you're grilling or frying the burgers. So, if you're looking for a crunchy texture and want to make sure your burgers don't fall apart, adding some breadcrumbs can be a great way to achieve that.
