Which ingredients are required for a Mexican Pizza?

The required ingredients for a Mexican Pizza at Taco Bell include beans and beef. This combination is traditional for the dish, as it forms the filling that is layered on top of tortillas. The use of refried beans provides a creamy texture, while the seasoned beef adds flavor and substance. This creates a satisfying and hearty pizza that embodies elements typical of Mexican cuisine.

While other options suggest various ingredients that could be associated with different Taco Bell menu items, only beans and beef specifically align with the authentic composition of a Mexican Pizza, capturing the intended taste and presentation of the dish.
