Sandwich Montpelliérain
One preparation carries Montpellier's name into a kitchen, and it is a spread: beurre de Montpellier, the green herb-and-anchovy butter Escoffier set down in 1903 for cold fish.

Sandwich Mogettes
The morning after a cassoulet, a Vendée cook crushes leftover mogettes against country bread for breakfast: the bare bean-on-bread reading, before any of the named restaurant pairings.
Sandwich Mixte
Mixed sandwich with multiple meats and/or cheeses.
Sandwich Métro
Named for where it is bought, not what is in it: the half-baguette grabbed at a Paris transit kiosk and eaten one-handed on the platform, built to survive the descent, the wait, and the first stops.
Sandwich Merguez
The Sandwich Merguez is a French open-air market and banlieue counter build organised around a North African chilli sausage, the lamb's heat carried in a baguette with frites and harissa.
Sandwich Merguez-Frites
The Maghrebi-French kebab counter's late-night build: two merguez, a bed of frites tucked inside the loaf, harissa and garlic mayo, paper around the lot.
Sandwich Méditerranéen
The sandwich méditerranéen is a coast in a loaf, not a recipe: ripe tomato, black olives, basil, and tuna or fresh cheese bound by olive oil brushed into the crumb until the bread drinks it.
Sandwich Marché
The sandwich du marché is a method, not a recipe: a baguette filled to order from the morning's stalls, ham off the block and a tomato out of the crate, eaten on foot before the bread tires.
Sandwich Maquereau au Vin Blanc
White wine-marinated mackerel on bread.
Sandwich Manceau
Rillettes du Mans, coarse pork slow-cooked in its own fat until it shreds, spread thick on a crusted loaf with cornichons pressed in. Shreddier and paler than the smoother Tours style.
Sandwich Magret Séché
No heat ever touches it. Magret séché is duck breast salted, peppered and air-dried for weeks until it slices translucent and deep red, the bird handled like a cured ham, shaved thin onto baguette.
Sandwich Magret de Canard
Seared rare and fanned on a baguette, the magret sandwich keeps one thick slice in two registers at once: a rendered fat rim and a rosy heart. Gascony's duck served the way other regions serve steak.
Sandwich Lyonnais
The bouchon pairing on a Lyon baguette: rosette de Lyon shingled along the crumb and cervelle de canut, the city's herbed fresh cheese, spread on the facing crust.
Sandwich Lorrain
The sandwich lorrain lifts the fillings of a quiche lorraine out of the shell: smoked lard fumé, egg, and a mild cheese on buttered bread, the eastern French table made portable.
Sandwich Lonzu
The Sandwich Lonzu shaves Corsica's leanest cure, the dry-cured pork loin, thin onto a buttered baguette: a herbed, near-lean coin with a hazelnut rim of fat and a chestnut-smoke note under it.
Sandwich Lentilles du Berry
A meatless French sandwich that exists because one regional lentil holds its shape: the lentille verte du Berry, dressed cold with shallot and vinegar, sits in bread as firm beads rather than a smear.
Sandwich Languedocien
There is no codified dish called the sandwich languedocien. The name is the Languedoc larder: cured pork, goat cheese, Lucques olive and garlic on a crusted loaf split for filling.
Sandwich Lamproie
Lamprey (eel-like fish) prepared à la bordelaise in sandwich; rare delicacy.
Sandwich Kouign-Amann
Sweet: kouign-amann pastry split and filled.
Sandwich Knack
The knack is named for the sound its casing makes: a clean crack under the teeth, then the juice. Scalded and lightly smoked, served warm under mustard, the cooked sausage on a cold charcuterie shelf.
Sandwich Kebab
France took the Berlin döner, jammed a fistful of fries inside the bread, drowned it in garlicky sauce blanche, and called it a grec. It is the default 2am meal of every French town, fries and all.
Sandwich Jésus de Lyon
Lyon's December sausage: the broadest, longest-cured of the Lyonnais saucisson family, hung in November and coined onto baguette through the Christmas week.
Sandwich Jambon de Vendée
Jambon de Vendée skips the drying room: dry-salted, rubbed with eau-de-vie and spices, then pressed instead of air-dried. Eaten thick-cut and often warm, an outlier among France's cured hams.
Sandwich Jambon de Bayonne-Brebis
A Basque sandwich where every part carries an address: dry-cured Bayonne ham, Ossau-Iraty sheep's cheese, and a streak of black-cherry jam from Itxassou. The cherry keeps salt-on-salt from going flat.
