Sandwiches are a mainstay on nearly every menu across the country. In this episode, Martha reimagines five classics. They include a juicy roasted chicken club, an iconic New Orleans po'boy piled high with oysters, an impressive muffuletta, an applewood-smoked bacon and fried-egg sandwich and a classic Reuben with succulent layers of corned beef, Swiss cheese and Russian dressing. Easy to make and portable, they'll inspire you to make each of them.
