Retreat to the fallout shelter because starting today, Taco Bell is detonating a flavor bomb. The new Grilled Cheese Nacho Fries is a savory combo of two comfort classics. Crunchy golden fries topped with melty grilled cheese; what more could your stomach ask for?

Along with a cheesy blend of mozzarella, monterey pepper jack, and cheddar, it also comes with marinated grilled steak drizzled with nacho cheese and chipotle sauce. If that isn’t enough to whet your appetite, you can also add jalapeños for a spicy kick.

Taco Bell’s new Grilled Cheese Nacho Fries are only $4.99 and available for a limited time only.
