Claiming that this is The Best Lunch Sandwich is a pretty bold statement… but if it wasn’t true, we wouldn’t say it! Toss aside that tired turkey and hand over the hum-drum ham, because these perfectly seasoned, deliciously grilled chicken breasts are way, way out of their league! The presentation of this handheld is everything, too. It has elevated condiments and has absolutely no time for boring, bland bread. You best believe that this is The Best Lunch Sandwich there is! Nothing else could ever compare!
