10 Things You Didn’t Know About the Publix Sub in Florida

Publix has been around since 1930.

The Pub Sub hasn’t.

The sandwich that defines the Publix deli today is younger than many of the people who line up to order it on Friday afternoons, and the story behind it is full of facts that even longtime Floridians get wrong.

Here are 10 things you didn’t know about the Publix Sub.

It Wasn’t Invented Until 1992

The Pub Sub feels like it’s been part of Publix forever.

It hasn’t.

The first custom Pub Sub menu was created in 1992.

Publix had been around for 62 years before the Pub Sub showed up.

Customers were already buying meat and cheese from the Publix deli. But the made-to-order sub with its own menu and customization was a 1990s invention.

It Wasn’t Born in Florida

Florida claims the Pub Sub, and Florida is right to love it.

But the sub didn’t start there.

It began in Marietta, Georgia, just outside Atlanta.

That’s where Publix store #33 rolled out the first custom sub menu in 1992, as the company was expanding into Georgia for the first time.

Floridians like to think the Pub Sub is theirs. We hate to break it to them, but it’s not.

Publix Won’t Officially Crown a “Sub Inventor”

There’s a popular online story that a guy named Dave and his friends in Georgia came up with the chicken tender sub in the mid-1990s.

Publix has politely declined to confirm it.

According to the Tampa Bay Times, Publix says the first corporate documentation for the chicken tender Pub Sub recipe was recorded in 1992 or 1993, at least four years before Dave’s group claims to have invented it.

There’s no definitive single inventor story.

Publix calls it a team effort.

The Chicken Tender Sub Is the Top Seller (And It’s Not Close)

Of all the Pub Subs on the menu, the chicken tender sub is the unquestioned #1.

It’s the sub that got Pub Subs onto national lists. It’s the sub that has its own fan-run website tracking when it goes on BOGO. It’s the sub that built the legend.

The chicken tenders are double hand-breaded.

That isn’t marketing fluff.

It’s the reason the breading stays crispy on a sandwich that gets loaded with sauce and vegetables.

A Half Chicken Tender Sub Clocks In at 660 Calories

The Pub Sub is delicious. The Pub Sub is also calorie-dense.

Per Publix’s nutrition data, a half (6-inch) chicken tender sub runs about 660 calories.

A whole 12-inch chicken tender sub with cheese, mayo, and full toppings can run close to 1,300 calories or more.

That’s not a knock on it.

It’s a fact of life that a fried chicken sandwich on a Cuban-style roll with cheese and aioli isn’t a diet food.

It’s also why so many people split a whole sub with someone else and call it two meals.

Half Subs Are Roughly 6 Inches and Whole Subs Are About 12

Publix uses “half” and “whole” instead of inch measurements.

Half sub = about 6 inches.

Whole sub = about 12 inches.

That’s not standardized to the millimeter, but it’s the rough Publix scale.

The half sub feeds one average person. The whole sub feeds one hungry person or splits between two.

The pricing structure rewards the whole sub if you’re feeding more than one.

There’s Industry Tracking When Pub Subs Go on BOGO

The chicken tender sub goes on BOGO several times a year, and Pub Sub fans plan their lives around it.

There’s a website called Chicken Tender Sub that lets you sign up for sale alerts.

There’s another site at Are Publix Chicken Tender Subs on Sale that’s exactly what it sounds like. There’s an X account called @PubSubs_on_sale that announces every BOGO.

There’s even a song titled “Publix Subs” with thousands of views on YouTube.

When the chicken tender BOGO hits, deli lines stretch through the bakery and around the cracker aisle.

People stockpile them. They freeze the second one for later. They tailgate them on Saturday college football mornings across the Southeast.

The BOGO is its own economy.

The Pub Sub Has Inspired Pilgrimages

Pub Sub fandom isn’t just a Southern thing anymore.

There’s a documented case of a customer driving 30 miles to get his preferred Publix sub. There are travel articles about northern transplants flying into Florida and going straight to a Publix from the airport.

Thrillist once called the Pub Sub one of the best sandwiches in the country.

People who move out of the Publix footprint, to Chicago or California or Colorado, talk about missing Pub Subs the way other people talk about missing a hometown bakery.

The sandwich travels well in a cooler. The longing for it travels even better.

You Can Build Almost Anything as a Pub Sub

The official Pub Sub menu shows the popular builds, but the deli will let you customize almost any combination.

Bread types: Soft Italian, Tutto Pugliese, white roll, whole wheat, flatbread, gluten-free wrap.

Sub formats: As a sandwich, as a wrap, or as a salad with no bread at all (called “in a bowl”).

Add-ons: Chicken tenders on any sub, double meat, double cheese, extra veggies.

The deli will mix meats and cheeses you’d never see on the printed menu. Half turkey and half ham. Roast beef with provolone and chipotle gouda. Italian with chicken tenders on top.

The menu is a suggestion. The real menu is whatever the deli has in stock.

Pub Subs Made the Leap From Sandwich to Cultural Symbol

The Pub Sub stopped being just a sandwich years ago.

It’s a recurring joke in Southern Twitter and TikTok. It’s gift wrapping at college tailgates. It’s the official welcome-to-Florida ritual for people moving in from out of state.

It’s been featured in Thrillist, Eater, The Kitchn, Reader’s Digest, and many national food publications.

The Publix marketing team didn’t engineer this.

Customers did it on their own.

A grocery store deli sandwich became a cultural symbol because enough people loved it enough for long enough that the rest of the country started paying attention.

The Pub Sub Earned Every Bit of Its Legend

The Pub Sub is one of the great American sandwiches, and it got there the hard way.

No celebrity endorsement. No flashy ad campaign. No franchise expansion across the country.

Just a deli counter in Marietta, Georgia, a custom menu in 1992, and a few decades of word-of-mouth from people who couldn’t shut up about it.
