What is cookout walkin taco?

As an AI language model, I do not have personal experience with Cookout Walkin Tacos, but I can give you some information that I have researched.

Cookout is a popular fast-food chain in the southern United States that offers various American-style burgers, hot dogs, tacos, and other fast food items. Cookout Walkin Taco is their unique take on a traditional Mexican dish, where they serve a bag of Fritos corn chips topped with seasoned beef or spicy chicken, shredded lettuce, and cheese. The taco bag can also be customized with toppings like diced tomatoes, jalapeños, onions, and sour cream. The 'Walkin' part of the name came from the ability to eat on the go as the taco ingredients are contained within the bag of chips. This option is popular among customers who are looking for a quick, tasty, and affordable food option on the go, especially during outdoor events, parties, or gatherings.
