The test item is basically the chain's regular Quesarito but with queso sauce in place of nacho cheese sauce. Specifically, it's a quesadilla made with two flour tortillas sandwiching queso sauce and shredded cheese wrapped up into a burrito filled with seasoned rice, seasoned beef, Creamy Chipotle sauce, and sour cream.
Taco Bell's queso sauce was first introduced in 2016 as a limited-time item and consists fire-roasted green chilies, onions, jalapenos, tomatillos, cheese, and a hint of cayenne.
The Queso Quesarito is priced at $2.99, which is about the same price as the regular Quesarito.
