What is the base ingredient for the Crunchwrap Supreme?

The Crunchwrap Supreme primarily features seasoned ground beef as its base ingredient, providing a hearty and satisfying flavor that is essential to the item. This savory meat is complemented by layers of other ingredients such as cheese, lettuce, tomatoes, and sour cream, all wrapped in a warm tortilla. While vegetables, black beans, and rice are also part of Taco Bell's menu and can be found in various dishes, they do not serve as the primary component of the Crunchwrap Supreme. The focus on seasoned beef helps to deliver the signature taste that customers associate with this popular menu item.
