A new foot-long snack option has appeared on Subway menus in the US: the 'Doritos Footlong Nachos.' They will stay on the menu 'for a limited time while supplies last,' Subway said.

Subway is adding footlong nachos to its Sidekicks menu. The sandwich chain has joined forces with Doritos for the new $5 dish. It features nacho cheese-flavored Doritos with cheddar cheese, jalapenos, tomatoes, red onions and a chipotle sauce.

Subway and Doritos have teamed up to introduce Doritos Footlong Nachos, available now at Subway restaurants for a limited time.
