I used a "buy one, get one" coupon and ended up getting a regular Homestyle version as well as one with a grilled chicken filet (it can also be custom ordered with the spicy chicken filet). The price was actually lower than the suggested price ($4.69) at $4.49 before the coupon.
This is pretty much the unofficial chicken follow-up of the Ciabatta Bacon Cheeseburger offered earlier this year. The only difference beyond the chicken is the lack of bacon (boooo!) and the roasted tomatoes and aioli are mixed together rather than separate.
