McDonald's McCrispy
A flat, wide white-meat fillet with crinkle-cut pickles on a toasted potato roll, breaded for an edge-to-edge crunch. McDonald's launched it on 24 February 2021, then renamed it McCrispy in 2023.
USA
McDonald's Filet-O-Fish
A steamed bun, a breaded pollock fillet, half a slice of American cheese, and a cold tartar on the crown. McDonald's chain-product reading of the 1962 Cincinnati Lent build.
McDonald's Big Mac
Why the Big Mac is the only sandwich measurable as a unit of currency: a published recipe, a fixed assembly order, and a three-part bun that braces every other choice in the build.
Maxwell Street Polish
Grilled Polish sausage on a bun with grilled onions and yellow mustard; Maxwell Street Market original.
Matzo Ball Soup Sandwich
Some delis serve matzo ball with chicken on bread; niche item.
Maple Bacon Burger
Candied bacon set on a patty: the maple bacon burger inherits the barbecue tradition of pig candy and the decade of bacon mania that put maple and pork on every menu.
Manapua
Hawaiian char siu bao (steamed pork bun); Chinese-Hawaiian.
Maine Lobster Roll
Cold picked lobster barely bound with mayonnaise and lemon, mounded on a toasted split-top roll. A lobster salad on a hot-dog bun, and the version most of the country pictures.
Maid-Rite
The branded Iowa loose-meat sandwich: finely ground beef cooked loose and dry, no tomato, on a steamed bun, franchised out of Muscatine in 1926.
Loose Meat Sandwich
A heap of seasoned ground beef, loose on a bun, eaten with a spoon. In Iowa it answers to three names locals refuse to swap, and one rule everyone keeps: no tomato.
Long Island Bacon Egg and Cheese
A kaiser-roll bacon, egg and cheese is the Long Island deli's standing morning order, built to hold a soft scramble against a crusty hard roll.
Lomi Lomi Salmon Sandwich
Lomi lomi salmon (cured salmon with tomatoes and onions) on bread.
Lobster Grinder
Picked lobster bound in mayonnaise or warmed in butter, packed into a foot-long sub roll over iceberg and tomato; the southern New England Italian-sub reading of lobster.
Livermush Sandwich
Fried livermush, pork liver bound with cornmeal by state-mandated ratio, on white bread with mustard or grape jelly; a Piedmont North Carolina breakfast staple centered on Shelby and Marion.
Lexington BBQ Sandwich
Pork shoulder smoked over oak, chopped, doused in the thin vinegar-and-ketchup "dip," and capped with red slaw dressed the same way. The Piedmont North Carolina build, and its one-ingredient line.
Korean-American Fried Chicken Sandwich
A double-fried boneless fillet brushed in gochujang or soy-garlic glaze, on a soft bun with kimchi slaw and pickled daikon. Bonchon's 2006 New Jersey arrival, on bread.
Knish
Not a sandwich, but potato or meat filling in dough; sometimes split and filled.
King Crab Sandwich
Whole red king crab leg meat on a roll, barely dressed in butter, built around an animal too costly to shred. Bering Sea legs from a fishery that peaked in 1980 and now runs on a strict quota.
Kentucky Burgoo Sandwich
A Kentucky communal stew cooked so thick a spoon stands in it, ladled open-faced over bread or cornbread. Burgoo is a kettle tradition first, a sandwich second.
Kansas City Reuben Dog
Hot dog topped with sauerkraut, Swiss cheese, and Thousand Island dressing; KC's Reuben-inspired hot dog.
Kansas City BBQ Sandwich
Kansas City puts the sauce in front: burnt ends or chopped pork on a plain bun under a thick, sweet tomato-and-molasses glaze that clings rather than cuts. The most sauce-forward barbecue city.
Kalua Pork Sandwich
Kalua pork is the leftover of an underground pit oven where shoulder cooks under banana leaves and hot stones for hours. When it ends up on a sweet roll, the bread is the smallest decision.
Juicy Lucy
Minneapolis stuffed burger: a slug of American cheese sealed inside two ground-beef patties so it melts molten and bursts when the crust is cut.
Jucy Lucy
The bartender slides it over and tells you to wait. Cheese sealed between two raw patties, now a molten pocket holding more heat than any slice on top. That one relocation is the whole burger.
