Hawaiian Plate Lunch Sandwich

At the walk-up window of Rainbow Drive-In on Kanaina Avenue in Kapahulu, the order moves fast and the format is understood: a teriyaki beef plate, or the same protein in a soft roll, built in the same sequence as the plate. The cook lays the protein across the bottom bun, spoons the macaroni salad against it, then packs in a scoop of white rice before the cap goes on. The foil closes around the whole thing and the sandwich comes through the window heavy and hot at the seam. The point of the format is not to replace the plate but to make it portable without losing the build.

What distinguishes this from a protein sandwich is the build order and what that order does to the texture inside. Rice sits against the bread before the protein, which means the bread absorbs the starch moisture from below while the teriyaki sauce runs down from above; the macaroni, cold-set and mayonnaise-bound, sits between the two and holds the fill from compressing into a single mass. The cold of the macaroni against the warm rice in the same bite is not a flaw the builder is trying to correct. It is the point. The three-temperature fill, warm protein, warm rice, cold mac, is what the plate gives and what the sandwich carries forward.

The build fails when the roll is wrong. A roll with a crusty exterior, a baguette or a sub roll, does not compress under the fill and the rice and macaroni spill through the bottom as the foil is peeled back. A roll too soft tears under the weight of the rice before the eater gets through the first half. The working roll is a butterflied soft white bun, yielding enough to settle around the fill without tearing, dense enough at the crust to hold the sauce. A macaroni salad too firm from cold-setting does not bind to the warm rice and the two starches split in the bite; a macaroni too wet soaks through the bread before the foil is fully open.

Peel the foil at the seam and the steam lifts off sweet from the teriyaki and faintly sour from the macaroni mayonnaise. The bread lip is hot and soft, with a thumb-dent where the rice has settled. The first bite is mostly bread and rice, the rice still slightly sticky against the upper palate; the macaroni arrives a moment later, cold and slick, and the teriyaki shows up dark and sweet at the back. The foil stains at the seam where the sauce has run down during the carry from the window.

Rainbow Drive-In opened at 3308 Kanaina Avenue in October 1961, founded by Seiju Ifuku and his wife Ayako after Seiju had cooked for the U.S. Army and worked the restaurant circuit in Honolulu. The walk-up window beside the parking lot and the partition-paper-plate lineup have stayed under the same family for more than sixty years since, now run by Seiju's grandson Chris Iwamura. The protein roster at the window, teriyaki beef, kalua pork, chicken katsu, Spam, fried mahi-mahi, is continuous with the plate-lunch menu; the sandwich is the plate in a different wrapper, not a separate product.

L&L Drive Inn on Liliha Street, the establishment Eddie Flores Jr. acquired in 1976 and eventually franchised into several hundred L&L Hawaiian Barbecue locations across the mainland, brought the plate-lunch menu to a national counter vocabulary. The sandwich versions on the L&L menu follow the same protein roster and the same two-scoop ratio. Zippy's runs a parallel lineup, and across all three the default is understood without specification: two-scoop rice, one-scoop macaroni, protein on top, soft roll around it.

Origin and history

The Hawaiian plate lunch traces to the partitioned lunch pails of the sugar and pineapple plantations from the 1880s into the 1910s. Laborers from Japan, China, Korea, the Philippines, and Portugal carried small tins to the fields, each compartment holding a starch, a vegetable, and a small protein from the worker's home cuisine. Lunch wagons serving the camps standardized the three-part format through the 1920s: a starch, a protein, and a second starch or vegetable, first on metal partition trays, later on paper plates.

The mayonnaise-bound macaroni salad arrived in the second half, with the American influence of the late territorial and post-statehood period. The mac salad, closer to a midwestern church-supper side than to anything in the Pacific tin-pail tradition, settled beside the rice scoop and the protein on the paper plate and the three-part composition was effectively codified by the 1950s. When that composition moved to a bun, the build order moved with it: the starch components did not become a side, they became the fill around the protein, which is what separates the plate-lunch sandwich from a teriyaki beef sandwich with a scoop of rice somewhere nearby.

Rainbow Drive-In's founding in 1961 and L&L's Liliha Street presence from 1976 established the two counters most associated with the format in its current form. There is no documented moment when a named cook or a published menu first folded the plate into a bun and called it a sandwich; the format appears to have evolved as a practical extension of the plate at counters already running both. The foil-wrap, standard at walk-up windows and drive-ins as early as the 1960s, made the portability argument available without requiring a documented invention.
