Build Your Own Vegan Sub
If you prefer to create your own sandwich, Firehouse Subs allows full customization.
Step 1: Choose Your Bread
The vegan-friendly bread options are:

The wheat bread contains honey, so it is not fully plant-based.

- Avocado
- Bell peppers
- Banana peppers
- Black olives
- Cucumber
- Lettuce
- Jalapeños
- Onions
- Mushrooms

- Dill pickles
For a more filling sub, doubling up on vegetables is always a good option.
Step 3: Pick a Vegan-Friendly Sauce
Not all dressings and sauces at Firehouse Subs are vegan, but these are:
- BBQ sauce
- Sriracha
- Mustard
- Marinara
- Oil and vinegar
- Balsamic vinaigrette
- Italian dressing (confirm the specific type with staff)
For extra flavor, mixing two dressings can be a great way to enhance your sub.
Vegan-Friendly Extras
If you’re looking for something on the side, these are the best vegan-friendly choices:
- Dill pickle spears – A simple, crunchy addition to your meal
- Chips – Some varieties are vegan, so check the packaging before ordering
What to Watch Out For At Firehouse Subs
While Firehouse Subs offers several vegan-friendly options, there are a few things to keep in mind.
- Cross-contamination is possible. Firehouse Subs prepares meat and dairy products in the same kitchen, so there is always a risk of cross-contact. If this is a concern, ask staff to use clean gloves when preparing your order.
- Confirm ingredient details. Some sauces and dressings contain hidden dairy or egg ingredients, so it’s always best to double-check.
- The Veggie Sub and salads come with cheese by default. Always request them without cheese to keep your meal fully plant-based.
Final Thoughts
Firehouse Subs may not have a dedicated vegan menu, but with a little customization, you can still enjoy a delicious plant-based meal.
Whether you choose a veggie-loaded sub or a fresh salad, there are plenty of ways to make it work.
Now that you know what to order, it’s easy to grab a satisfying, vegan-friendly meal the next time you stop by Firehouse Subs.
