November 26, 2025 •

3 min read

According to a 2025 survey by Veganuary, over 25 million people tried a vegan diet, with many seeking plant-based fast-food options. This increased demand raises the question: is a veggie sub vegan, or do you need to make customizations to ensure it fits your dietary needs?

Quick Summary

A veggie sub is not always vegan by default; it depends on the bread, cheese, and sauces used. This guide explains how to customize a veggie sub at popular chains like Subway to ensure it is completely plant-based, covering all ingredients from the ground up.

Key Points

Veggie Sub is Not Always Vegan: Many standard veggie subs contain non-vegan ingredients like milk, egg, or honey in the bread, cheese, or sauces, requiring careful customization.
Check Your Bread: While Italian, Sourdough, and some multigrain breads are vegan at Subway, others like Flatbread and those containing cheese or honey are not.
Beware of Sauces and Dressings: Many creamy sauces are dairy-based. Stick to safe options like oil and vinegar, yellow mustard, or sweet onion sauce.
Vegan Cheese Availability Varies: Vegan cheese is not a standard offering and must be requested specifically, and it is not available at all locations.
Confirm the Veggie Patty: Some chains have updated to a vegan patty, but availability is inconsistent. Always verify if the veggie patty is plant-based at your specific location.
Prevent Cross-Contamination: To ensure a strictly vegan meal, politely ask staff to change gloves and use fresh utensils.

Understanding the Veggie Sub: More Than Just Vegetables

For many, a 'veggie sub' seems like an obvious vegan choice, but the reality is more nuanced. While the vegetable fillings are typically plant-based, ingredients in the bread, cheese, and sauces can contain animal products like milk, eggs, or honey. Therefore, to ensure your veggie sub is truly vegan, a careful approach to ordering is required. This guide will walk you through the specifics at a major fast-food chain like Subway and provide general principles for any other sandwich shop.

The All-Important Foundation: Vegan Bread Options

The most common non-vegan surprise in a sub is the bread itself. Many breads, including some 'wheat' or 'multigrain' options, may contain honey, dairy, or egg wash.

Safe Choices: At Subway, the Artisan Italian (white), Hearty Multigrain, and Sourdough are reliably vegan in most regions. Some locations may offer other vegan-friendly options like Roasted Garlic bread.
Unsafe Choices: Flatbreads and wraps often contain milk. Always avoid breads with 'cheese' or 'honey' in the name. The availability of specific vegan bread options can also vary by country or franchise, so checking the nutritional guide is best.

Beyond the Bread: The Crucial Role of Toppings and Sauces

This is where most mistakes happen. While all standard vegetables are safe, many popular creamy dressings, condiments, and certain patties are not.

Vegetables: All standard vegetable toppings are vegan, including lettuce, tomatoes, cucumbers, green peppers, red onions, spinach, jalapeños, olives, and pickles. Avocado is another safe, plant-based add-on.

Cheese: Most fast-food chains do not use vegan cheese as their standard offering. At Subway, the regular cheese options are not vegan. You must specifically ask for vegan cheese if the location offers it.

Sauces and Dressings: The vast majority of creamy sauces, like Ranch, Chipotle Southwest, and mayonnaise, are not vegan.

Vegan Sauces: Safe condiment choices typically include yellow mustard, oil and red wine vinegar, and some barbeque sauces. The Sweet Onion sauce or Sweet Onion Teriyaki is also generally considered vegan.
Non-Vegan Sauces: Avoid anything with honey, dairy, or eggs, which includes many specialty dressings and mayonnaise-based spreads.

The Verdict on Veggie Patties

The veggie patty is another item that requires scrutiny. In the past, many veggie patties were not vegan due to the inclusion of egg or dairy protein. However, some chains have updated their recipes. For example, some Subway locations reformulated their veggie patty to be plant-based in recent years, but availability is not consistent across all US restaurants. Some regions may have completely different options or none at all, making it essential to verify at your specific location.

Customizing Your Vegan Veggie Sub: A Step-by-Step Guide

Start with the Right Bread: Choose a confirmed vegan bread like Artisan Italian or Sourdough.
Request Fresh Gloves: Politely ask the sandwich artist to change their gloves to prevent cross-contamination from meat and cheese.
Go Wild with Veggies: Load up on all the fresh, crunchy vegetables. Don't forget avocado for creaminess.
Hold the Dairy: Specify no cheese. If available, ask for vegan cheese.
Choose a Safe Sauce: Opt for oil and vinegar, yellow mustard, or sweet onion sauce.

Conclusion: Navigating the Nuances for a Truly Vegan Meal

In conclusion, a veggie sub is only vegan if it's customized correctly. Simply ordering the standard item without meat is not enough, as non-vegan ingredients are often hidden in the bread, cheese, and sauces. By following the simple steps of selecting vegan-safe bread and condiments and confirming with the staff, you can confidently enjoy a delicious and truly plant-based meal from a fast-food chain. Always remember to check for potential cross-contamination to ensure a fully vegan experience.
