I can say I used to work at Publix, they will let you sample anything, also they have a money back guarantee, you can eat the whole sub and if you don't like it and you have your receipt they will give you a full refund. So nothing to lose.
I had one today. Terrible. Awful. cilantro and carrots? yuck... meat was tough, stringy, and chewy. overall very dry. typical poor attempt at being exotic. I'm stickin with my sweet onion chicken teryaki from Subway.
