Forget food trucks and crepe stands. When Parisians want a quick, easy meal, they head to the local boulangerie and order a jambon-beurre—"un mixte, s’il vous plaît!" The best sandwiches are the simplest: a thick slice of country ham nestled between butter-spread halves of a freshly baked baguette. Ensconced in an old chevaline (horse butcher shop) replete with 1950s decor, Chez Aline is a fast-food deli with a reputation for the best jambon-beurre in the city. Chef Delphine Zampetti offers a selection of other sandwiches, salads, and desserts to curb your hunger.
