Just got done with this, and here are some impressions:
The "ciabbata (sp?) bread" tastes like sweet raw bread dough. I ate half the sandwich, then threw the rest of the bun away. The texture was very squishy and dense. Frightening.
The chicken has a good flavor from the grilling--like something you'd make on a gas grill yourself. The chicken was tender as the name implies, but nothing amazing. A bit salty, but not overly so.
Paltry amount of lettuce and tomato, with the mayo dripping off like liquid.
Not really worth buying again IMO.
