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!
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.
Bread:
- 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

- Tomato
Vegan condiments:
- Balsamic Dressing

- Italian Salad Dressing
- Marinara Sauce
- Spicy Mustard
- Sriracha 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

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

- 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.
