Unbelievable Sandwiches from Around the World

Banh mi (pronounced "bun mee") masterfully combines a crisp baguette with a succulent filling, such as tangy-salty grilled chicken, and bracing toppings, from chilies and cilantro to cucumbers to pickles. Once a trendy food, it has now settled into the realm of classic-Asian-sandwiches-Americans-love-to-eat; and now, established food writer Andrea Nguyen has devoted an entire book to the subject, aptly titled The Banh Mi Handbook. Her advice: Be choosy about the bread but don't suffer over it; a toaster oven can be your best ally for reinvigorating a soft baguette.
