The popular popcorn chips, now made with a patented blend of corn, sunflower and potato, will now come in a whole-grain version.
But the chain is not taking away the corn chips, which are the centerpiece of its new Subway sandwich.
The chips have always been available in the same pack, but now they will be available in a more flavorful, whole-wheat-meal version, a spokesman for Subway said.
The company is adding more toppings, including lettuce, tomato and onion, he said.
Mr. Smith said Subway’s sandwich was named for its owners, brothers Tom and Bob Smith.
Mr., a native of Philadelphia, began buying and eating Subway in the mid-1990s, when he moved to New York from the Midwest.
Now the chain employs about 100 people in Brooklyn, Manhattan and the Bronx, where he grew up.
The brothers said they were happy to be part of a company with a strong heritage, but they had never seen a real change.
“We’re thrilled that Subway has brought back the classic sandwich and will be offering it to customers in New York and around the world in the coming months,” Mr. and Mrs. Smith wrote on Twitter.
