With most of America rooting for the Eagles in the Super Bowl, cheesesteaks are are having a moment. Theyโ€™re being mentioned in national news articles, being pitched by PR firms, cresting a five-year peak on Google Trends and showing up on menus across the country.

But most people are getting them wrong.

For some reason, when out-of-towners create variations on the classic Philly sandwich, they always add bell peppers.

Which, as just about any true Philadelphian will tell you, is not canon. A cheesesteak is meat, cheese, bread and sometimes onions โ€” and thatโ€™s it.

Thereโ€™s even a Facebook group dedicated to the banishment of green peppers from the cheesesteak ingredient list. Local purveyors also hold this belief. Asked whether those strips of vegetable belong on a classic cheesesteak, most shop owners Billy Penn contacted were firmly in the negative camp.

โ€œNO,โ€ was the definitive answer from Frank Olivieri, third-generation owner of Patโ€™s King of Steaks, the tourist destination considered the sandwichโ€™s birthplace.

Olivieriโ€™s sentiment was echoed by Steve Iliescu, founder of Steveโ€™s Prince of Steaks, whose daughter Abbe Arno relayed the message via email. โ€œHe does have an opinion,โ€ she wrote. โ€œThey do not.โ€

So followed Barry McGuinn, owner of Barryโ€™s Steaks (winner of Billy Pennโ€™s 2016 Ultimate Cheesesteak Bracket). โ€œI do not believe green peppers should automatically go on a cheesesteak,โ€ he said.

โ€œTradition is Kraft Cheez whiz and sauteed onion,โ€ offered Ethel, matriarch at Chubbyโ€™s Steaks, sounding a bit like a broken record.

So whereโ€™d the idea that peppers have a place on a cheesesteak come from? Unclear.

No doubt that the internet has helped the misconception spread. An image of green-pepper-ified meat and cheese has proliferated on Twitter food porn accounts for years.

A Tasty recipe video for cheesesteak skewers spiked with bell peppers went viral (BuzzFeed then apologized for getting it wrong). A pepper-filled ESPN recipe published just a few months ago generated lots of backlash.

But the truth is that green peppers are actually pretty popular on cheesesteaks โ€” right here in Philadelphia.

Yes, most local cheesesteak spots do offer the topping. Even Genoโ€™s, which was a holdout when stubborn founder Joey Vento was running it, has softened under second-gen owner Geno Vento. The neon-lit East Passyunk destination now offers the option to toss peppers in the roll.

Peppers have been available across the street at Patโ€™s for decades, said Olivieri, who estimates probably 40 percent of sandwich orders at the 88-year-old stand include peppers.

At Chubbyโ€™s the number of green-peppered cheesesteaks ordered is around 25 percent, and at Barryโ€™s, around one fifth of people ask for them. The Center City outpost of Steveโ€™s sees so many out-of-town customers that approximately 60 percent opt for peppers, said Arno, who added that โ€œmost locals do notโ€ get them.

Ken Silver, president of Jimโ€™s South Street, is more lenient than his compatriots.

โ€œWe sell peppers on roughly 25 percent of the sandwiches sold,โ€ Silver said, โ€œand wouldnโ€™t begin to question the authenticity of getting them on a sandwich.โ€

His shop has offered peppers since what he called โ€œthe early days.โ€ They used to be cooked by hand, when a good day of business meant a couple hundred sandwiches went flying out the door. Now that itโ€™s thousands served daily, he buys high-grade canned peppers from Mexico โ€” โ€œa nice variety of red, green and yellow cut thin.โ€

Silver compared Philadelphiansโ€™ dogmatic insistence that peppers are wrong to the idea that the only proper way to order a cheesesteak is with Whiz.

โ€œWhiz wasnโ€™t around for the first 20 years of the cheesesteakโ€™s existence!โ€ he noted.

McGuinn, of Barryโ€™s Steaks, prefers a plain steak with fried onions, but admitted even he sometimes opts for peppers to change things up.

โ€œSomething like that is a matter of taste. [Peppers] are very good on a cheesesteak,โ€ he said. โ€œI personally have them on occasion.โ€
