 Here, the Big Cheese at Crunchwrap Supreme and Tostada from Taco Bell. Built on the 16X Cheez-It platform, with the first flavor matrix stable enough to make a cheese at Tostada possible, and cheesy enough to power a Crunchwrap. Because if you want to change the world, you have to bring something big to the table. Think big, and order the Big Cheese at Crunchwrap Supreme and Tostada from Taco Bell. And participate in U.S. Taco Bell locations for a limited time only, while supplies last. Contact store for participation, which varies.
