Which burger is characterized by its mixture of black beans and brown rice?

The mixture of black beans and brown rice is a defining characteristic of a veggie burger. Veggie burgers are typically made from various plant-based ingredients designed to replicate the texture and flavor of a traditional meat burger, providing a meatless option. By combining black beans and brown rice, this burger not only delivers protein but also offers a hearty texture and a satisfying flavor profile suitable for those seeking a vegetarian or health-conscious option.

The other choices represent traditional meat-based options or specific regional styles, which do not include the black bean and brown rice combination that defines a veggie burger.
