I bought one for $4.29.
This was a little bit like Taco Bell's answer to a crispy chicken sandwich. There were two strips of crispy chicken inside and, while they were lightly seasoned, spicy, and reasonably crispy for steaming inside of the tortilla, the coverage was a little spotty. They shifted a bit inside the tortilla, which led to some meatless bites. It might be better if had they sliced up the chicken or folded a tighter package.
There's not too much flavor to the lettuce, tomatoes, and cheese and all of it seemed to be covered up by Mango BBQ sauce. Given the barbecue sauce, I felt like some onions, fried or otherwise, might have done better.
