What filling is found in a Bean Burrito?

The filling found in a Bean Burrito is beans, which is why this option is the correct one. The Bean Burrito is a classic item on Taco Bell's menu, primarily consisting of refried beans as the main filling. This creates a vegetarian option that is also rich in protein and fiber, appealing to a range of customers looking for meatless choices. The beans contribute not only to the flavor but also to the texture and nutritional value of the burrito.

The other options are not correct because they pertain to different menu items at Taco Bell. Chopped beef typically refers to fillings used in items like tacos or burritos that are meat-centric. Bacon is often found in breakfast items or some specialty snacks, while chicken is a common protein choice in other burrito variations or quesadillas. None of these options align with the primary filling of a Bean Burrito, which is distinctly beans.
