(Irvine, CA) -- Taco Bell is testing a new menu item featuring a giant Cheez-It. The new "Big Cheez-It Tostada" features layers of ground beef, sour cream, lettuce, tomatoes, and cheddar cheese on a Cheez-It 16 times larger than the standard. The large cracker will also pop up in the "Big Cheez-It Crunchwrap Supreme." Taco Bell describes the new products as an "abundantly cheesy and nostalgic" dining experience. They're on sale at one Irvine, California, location for the next two weeks.
