Sun Dried Tomato Tuna Sub: Allergens at a Glance
The honest verdict
Sun Dried Tomato Tuna Sub
This specialty sub combines tuna salad (canned tuna mixed with mayonnaise) with sun dried tomatoes on a sub roll. The tuna itself is the fish allergen source. The sub roll provides wheat and likely sesame seeds. The mayonnaise in the tuna salad introduces egg. Sun dried tomatoes are often packed in oil, which may be soybean oil (soy). Cheese is optional but common, adding milk. The sub is assembled on shared deli surfaces where cross-contact with other meats, cheeses, and spreads is possible. Always confirm the specific recipe and preparation with your restaurant before ordering.
Allergen details change and vary by location. This is a general guide — always confirm with the restaurant before ordering. Not official or medical advice.
Key facts
Tuna is a direct fish allergen source — this sub is not suitable for anyone with a fish allergy.
FDA — Food Allergen Labeling and Consumer Protection Act (FALCPA)
Mayonnaise in tuna salad is the primary egg source — egg-free alternatives exist but are not standard.
Shared deli preparation surfaces are a documented route for cross-contact between different meat, cheese, and spread allergens.
Every major allergen, one clear grid
Each of the nine major allergens marked for Sun Dried Tomato Tuna Sub — Contains, May contain (cross-contact or varies), or Free. Anything we couldn't confirm defaults to "may contain," because a shared kitchen can't be ruled out without the restaurant's official menu.
| Allergen and notes | Status |
|---|---|
Milk Milk is not a core ingredient in the tuna salad itself, but cheese is a common addition to this sub. The sun dried tomato spread or pesto variant may also contain dairy (parmesan or cream). Ask if cheese is standard and whether the spread contains milk. | May contain |
Egg The tuna salad is almost always made with mayonnaise, which contains egg. Some restaurants use egg-free mayo alternatives, but standard preparation includes egg. Confirm with the restaurant if egg allergy is a concern. | Contains |
Wheat / Gluten The sub roll is wheat-based. This is the primary wheat source. No standard gluten-free sub roll is available at most deli-style chains. A lettuce wrap or gluten-free bread alternative would remove the wheat. | Contains |
Soy Soy may appear in the mayonnaise (soybean oil) or in the oil used to pack sun dried tomatoes. Refined soybean oil is FDA-exempt from allergen labeling and tolerated by most with soy allergy, but those with severe soy sensitivity should ask about the specific oil used. | May contain |
Peanut Peanut is not a typical ingredient in tuna salad, sub rolls, or sun dried tomatoes. Cross-contact is very unlikely in a standard deli environment. | Free |
Tree Nut Tree nuts are not a standard ingredient in this sub. Pesto variants may contain pine nuts (a tree nut) — ask if the sun dried tomato spread is pesto-based. | Free |
Fish Tuna is the primary protein and a direct fish allergen source. This is the defining allergen of the sub. There is no fish-free version of this item. | Contains |
Shellfish Shellfish is not an ingredient in tuna salad or standard sub toppings. Cross-contact is not expected in a typical deli setting. | Free |
Sesame Sub rolls are commonly topped with sesame seeds. Some restaurants use sesame-free rolls — ask specifically whether the sub roll contains sesame. The sun dried tomato spread itself is not a sesame source. | May contain |
“May contain” means cross-contact is possible or the answer varies by location — not that the allergen is a listed ingredient. For a severe allergy, treat “may contain” the same as “contains” until the restaurant confirms otherwise.
Small changes that remove an allergen
Simple modifications that can take an allergen off your sun dried tomato tuna sub. Always name your allergy when you order and ask staff to confirm — a modification only helps if the kitchen prepares it separately.
Request the sub on a gluten-free roll or lettuce wrap instead of a standard sub roll
Order without cheese and ask if the sun dried tomato spread contains dairy
Ask if the tuna salad uses egg-free mayonnaise
Request a sesame-free roll or a wrap without sesame seeds
A modification lowers exposure but doesn't erase cross-contact from shared fryers, grills, or prep surfaces. For a severe allergy, confirm the prep with a manager before you eat.

Cross-contact & severe allergies
A “free of” mark on the grid above means the allergen isn't an ingredient — it doesn't mean the item was made in an allergen-free kitchen. Two things matter most:
Shared fryers & equipment
Deli-style sub shops use shared preparation surfaces, knives, and gloves. Tuna salad is often scooped from a shared container where utensils may contact other allergens. The sub roll is sliced on the same cutting board used for other breads and meats. Cross-contact with milk (cheese), wheat (other breads), and egg (other mayo-based salads) is possible. Ask the staff to change gloves and use a clean preparation surface for your order.
If your allergy is severe
For anaphylactic allergy to fish, wheat, egg, or milk, confirm every ingredient and preparation step with the restaurant before ordering. A sun dried tomato tuna sub is not guaranteed safe for any of these allergens without direct restaurant confirmation. Carry your epinephrine auto-injector. If you cannot confirm the ingredients, choose a simpler item with fewer components.
This guidance is general and can't account for how any single location prepares your food. The restaurant's staff and official allergen menu are the final word — when in doubt, ask, or choose something else.
Avoidance is not the only option for egg allergy
There is no FDA-approved immunotherapy for egg allergy. Some specialist centres offer egg oral immunotherapy off-label, and Xolair is approved to reduce the severity of reactions to accidental exposure across IgE-mediated food allergies.
Beyond that, oral immunotherapy in a specialist clinic raises reaction thresholds the most of any current approach, and sublingual immunotherapy raises them less but causes markedly fewer reactions and is easier to keep up over years. Neither makes any particular dish safe to eat, and an epinephrine auto-injector stays with you throughout.
A history of anaphylaxis, or severe or poorly controlled asthma alongside the food allergy, means this belongs with an in-person allergist rather than any remote service.
Frequently Asked Questions
Yes, tuna is the primary protein and a direct fish allergen source. This sub is not suitable for anyone with a fish allergy. There is no fish-free version of this menu item. If you have a fish allergy, choose a different sub with a non-fish protein like turkey, ham, or a vegetarian option.
No, the standard sub roll is wheat-based and contains gluten. Some restaurants offer gluten-free bread or lettuce wrap alternatives — ask if these are available. Even with a gluten-free roll, cross-contact from shared toasters or cutting boards is possible, so request a clean preparation surface.
Yes, standard tuna salad is made with mayonnaise, which contains egg. Some restaurants offer egg-free or vegan mayonnaise alternatives, but this is not the default. If you have an egg allergy, ask the restaurant whether their tuna salad uses egg-free mayo, and if not, whether they can prepare a custom portion without mayonnaise.
Sun dried tomatoes are typically just dried tomatoes, sometimes packed in oil. The oil may be soybean oil (soy concern) or olive oil (generally safe). Some restaurants use a sun dried tomato spread that may contain dairy (parmesan, cream cheese) or pine nuts (tree nut). Ask the restaurant for the specific ingredients of their sun dried tomato preparation or spread.
Yes, many sub rolls are topped with sesame seeds. This is a common practice at deli chains and sub shops. Some locations offer sesame-free rolls upon request. Always ask about the roll type when ordering for a sesame allergy. The sun dried tomato spread itself is not a sesame source.
