Which item is part of the Power Menu Bowl?

The Power Menu Bowl at Taco Bell is designed to be a customizable meal option that includes several protein choices, and chicken is one of the primary proteins offered in this bowl. Chicken adds a significant source of lean protein, making it a popular choice for customers looking for a balanced meal. The Power Menu Bowl allows customers to enjoy a mix of ingredients, including rice, beans, lettuce, and an array of toppings, but chicken specifically is highlighted for its appeal among those seeking a protein-rich option. This is why chicken is identified as a part of the Power Menu Bowl menu offerings.

Other options like ground beef, fish, and beans may be available in different products or meals within the Taco Bell menu but are not specifically recognized as a core part of the Power Menu Bowl. The focus on chicken in this particular question emphasizes the signature offerings of this customizable bowl.
