Here’s Every Vegan Option at Firehouse Subs

Firehouse Subs isn’t at the top of my list for vegan-friendly places to eat. That said, the easily customizable nature of a sub makes it doable for sure. You can get exactly the ingredients you want, nothing you don’t. The bread can be pretty filling, too.

Vegan options at Firehouse Subs:

  • Veggie Sub (No Cheese, No Mayo)
  • White Sub Roll
  • Gluten Free Sub Roll
  • Chips
  • Pickle Spear
  • Firehouse Salad (No Meat, No Cheese)
  • Chopped Side Salad (No Cheese)
  • Toppings and Condiments
  • Beverages

More details on all these below. Generally, you should get the customized Veggie Sub, or build a sub with White or Gluten-Free bread. See full lists of toppings and condiments below—including which ones aren’t vegan—and my #1 tip for making the Veggie Sub more filling!

I’ll end with a whole-food plant-based guide to Firehouse Subs, in case you’re trying to avoid fried and processed foods food, too!

Firehouse Subs Vegan Menu

The hot sauce selection at Firehouse Subs.

To make this vegan menu, I contacted Firehouse Subs directly, and they just directed me to the allergen menu and nutritional info on their website. Since full ingredients are listed on the website, that was all I needed.

So the following menu is solidly vetted as vegan. That said, it never hurts to ask for confirmation with your local Firehouse staff on any details you need help with.

1. Veggie Sub (No Cheese, No Mayo)

You can order the Veggie Sub to be vegan. It comes vegetarian already—you just need to ask for no cheese and no mayo. These will be the remaining toppings:

  • Sauteed bell peppers
  • Sauteed mushrooms
  • Sauteed onions
  • Raw onions
  • Lettuce
  • Tomato

Personally, I would have them add as much avocado as possible. It’s generally the one vegan topping they have which will really make your sub more filling.

2. Build Your Own Sub

If the “Veggie” doesn’t really resemble what you want, you can also build your own vegan sub from the ground up.


  • White Sub Roll
  • Wheat Sub Roll (contains a small amount of honey)
  • Gluten Free Sub Roll

Sub toppings:

  • Au Jus Bell Peppers
  • Au Jus Mushrooms
  • Au Jus Onions
  • Avocado
  • Black Olives
  • Cherry Pepper Rings
  • Chopped Green Peppers
  • Chopped Pickle Spear
  • Iceberg Lettuce
  • Onion
  • Pickle Spear
  • Tomato

Vegan condiments:

  • Balsamic Dressing
  • Cajun Seasoning
  • Italian Salad Dressing
  • Marinara Sauce
  • Spicy Mustard
  • Sriracha Sauce
  • Sweet Baby Ray’s BBQ Sauce

Note: The Jerk Mustard, Sweet Mustard, and Captain Sorensen’s Datil Pepper Hot Sauce are not vegan due to fish. The Italian Seasoning is not vegan due to milk.

3. Salads (No Cheese)

You can order either of the following two salads vegan. The main difference is that the Firehouse Salad is bigger and contains more peppers:

  • Firehouse Salad: Romaine, tomato, bell pepper, pepperoncini. Hold the cheese, choose “No Meat,” and pick a vegan dressing from below.
  • Chopped Side Salad: Romaine, tomato, bell pepper, cucumber. Hold the cheese and pick a vegan dressing from below.

Salad add-on toppings:

  • Banana Peppers
  • Black Olives
  • Jalapeno Peppers
  • Oil & Vinegar Dressing

Vegan salad dressings:

  • Balsamic Dressing
  • Italian Dressing
  • Oil & Vinegar

Note: The Light Italian Dressing is not vegan due to containing cheese.

4. Chips

Typical selection of vegan chips may include:

  • Sun Chips Original
  • Lay’s Classic
  • Lay’s BBQ Chips
  • Baked Lay’s
  • Ruffles
  • Fritos

5. Pickle Spear

You can also get a big pickle spear with your sub—it’s vegan, too!

But What About…

Here’s a list of menu items that you might think would be vegan, but they’re not:

  • The Wheat Sub Roll is not strictly vegan—it contains a small amount of honey.
  • The Coleslaw is not vegan—it contains eggs and fish.
  • None of the cookies are vegan—they all contain eggs and milk.
  • The Light Italian Dressing is not vegan—it contains cheese.
  • The Jerk Mustard and Sweet Mustard are not vegan—they contain fish.
  • Captain Sorensen’s Datil Pepper Hot Sauce is not vegan—it contains fish.
  • The Italian Seasoning is not vegan—it contains milk.

Whole-Food Plant-Based Options

What if you’re not just trying to eat vegan at Firehouse Subs but also whole-food plant-based (WFPB)? Can you fill up while avoiding fried and processed foods and animal products?

For a strict WFPB meal at Firehouse Subs, you might only really have the salads to work with. Oh, and the pickle. But none of the breads at Firehouse are strictly WFPB.

The wheat bread would be the closest option if you want to be a bit more flexible and build yourself a veggie sub with that. I’d avoid the sautéed vegetables, as I’m assuming oil and/or a sugary sauce is used for sautéing.

1. This is the best free video training I’ve found on plant-based nutrition. You’ll learn how to reduce your risk of cancer, heart disease, type 2 diabetes, Alzheimer’s, and obesity—all with plant-based food. Watch the free “Food for Health Masterclass” here.

2. This is the best vegan multivitamin I’ve found in my 14 years of being vegan. It has vitamin B12, vitamin D, omega-3—and nothing else. Translation: It only has the nutrients vegans are actually low in. Read my full review of Future Kind’s multivitamin here (with 10% discount).
