Mediterranean Steak Sub: Allergens at a Glance
The honest verdict
Mediterranean Steak Sub
A Mediterranean steak sub is a sandwich built on a sub roll with sliced steak, Mediterranean-style toppings (feta or provolone cheese, lettuce, tomato, onion, peppers), and a sauce like tzatziki, garlic aioli, or vinaigrette. The allergen profile is anchored by wheat from the roll, milk from the cheese and tzatziki, and soy from the steak seasoning or sauce. Egg may be present in the roll or aioli. Sesame may appear on the roll or in tahini-based sauces. The steak itself is typically a single-ingredient protein, but marinades and seasonings can introduce soy, wheat, or other allergens. Cross-contact from shared grills, cutting boards, and utensils is a real concern. This is a restaurant-specific item — there is no single national chain standard. Always verify the exact ingredients and preparation methods with the restaurant before ordering.

Key facts
Sub rolls are wheat-based, making the bread the primary source of gluten in a Mediterranean steak sub.
FDA — Food Allergen Labeling and Consumer Protection Act (FALCPA)
Tzatziki sauce is yogurt-based and contains milk; aioli sauces contain egg — both are common on Mediterranean subs.
Shared grills and prep surfaces in restaurants are a documented route for cross-contact with milk, wheat, and soy.
Every major allergen, one clear grid
Each of the nine major allergens marked for Mediterranean Steak 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.
- MilkContains
Milk is present in the cheese (feta, provolone, or mozzarella) and in tzatziki sauce, which is yogurt-based. Some sub rolls may also contain milk. If you are dairy-free, request no cheese and a non-dairy sauce like vinaigrette.
- EggMay contain
Egg may be present in the sub roll (enriched dough) or in a garlic aioli or similar sauce. Not all sub rolls contain egg — ask the restaurant about their specific bread recipe and sauce ingredients.
- Wheat / GlutenContains
The sub roll is wheat-based. This is the primary source of wheat in the sandwich. There is no standard gluten-free sub roll at most restaurants. A lettuce wrap or gluten-free bread alternative may be available — confirm with the restaurant.
- SoyMay contain
Soy may be present in the steak seasoning, marinade, or in sauces like aioli or vinaigrette. Soybean oil may be used in cooking the steak or in the sauce. Refined soy oil is FDA-exempt but may still be a concern for those with severe soy allergy. Ask the restaurant about their specific ingredients.
- PeanutFree
Peanut is not a typical ingredient in a Mediterranean steak sub. The risk of peanut cross-contact is very low in this type of sandwich preparation.
- Tree NutFree
Tree nuts are not a standard ingredient in a Mediterranean steak sub. Some specialty sauces or pesto-style spreads could contain pine nuts or walnuts — ask if a nut-based sauce is used.
- FishFree
Fish is not an ingredient in a Mediterranean steak sub. Anchovy paste could theoretically appear in a Worcestershire-style marinade or Caesar dressing, but this is uncommon. Confirm with the restaurant if you have a fish allergy.
- ShellfishFree
Shellfish is not an ingredient in a Mediterranean steak sub. The risk of shellfish cross-contact is very low.
- SesameMay contain
Sesame may be present on the sub roll (sesame seed bun) or in a tahini-based sauce. Some Mediterranean restaurants use tahini in dressings or spreads. Ask the restaurant whether their roll is seeded and whether any sauces contain tahini.
“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 mediterranean steak sub. Always name your allergy when you order and ask staff to confirm — a modification only helps if the kitchen prepares it separately.
Order without cheese and tzatziki sauce
Request a lettuce wrap or gluten-free bread instead of the sub roll
Ask for a vinaigrette or oil-based dressing instead of aioli or tzatziki
Verify the steak seasoning and sauce ingredients for soy and sesame
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
Shared grills, cutting boards, and utensils in a restaurant kitchen mean the steak, vegetables, and bread can pick up trace allergens from other menu items. If the same grill is used for cheese-topped items or breaded proteins, cross-contact with milk, wheat, or soy is possible. Ask the restaurant about their prep surface and utensil practices for allergen-sensitive orders.
If your allergy is severe
For anaphylactic allergy to wheat, milk, soy, or sesame, confirm every ingredient and preparation step with the restaurant before ordering. A Mediterranean steak sub is not guaranteed safe for any of these allergens without restaurant-level confirmation. Carry your epinephrine auto-injector. If you cannot confirm preparation details, consider a simpler protein-and-vegetable plate without the bread and sauce.
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.
❓Frequently Asked Questions
Yes, typically. The cheese (feta, provolone, or mozzarella) and tzatziki sauce (yogurt-based) are direct sources of milk. Some sub rolls may also contain milk. If you are dairy-free, request no cheese and a non-dairy sauce like vinaigrette or olive oil. Confirm the roll ingredients with the restaurant.
No, not in its standard form. The sub roll is wheat-based. Some restaurants offer a gluten-free bread option or a lettuce wrap — ask about alternatives. The steak and vegetables are naturally gluten-free, but confirm that the steak seasoning and any sauces are also gluten-free, as soy sauce or Worcestershire sauce can contain wheat.
Common sauces include tzatziki (milk from yogurt, may contain egg), garlic aioli (egg, may contain soy), and vinaigrette (may contain soy or sesame). Each sauce adds a different allergen profile. Ask the restaurant which sauces they use and request one that matches your allergen needs. A simple olive oil and vinegar dressing is often the safest choice.
Plain steak is a single-ingredient protein and is free of the Big-9 allergens. However, many restaurants marinate or season the steak with spice blends, soy sauce, Worcestershire sauce (contains anchovy/fish), or other flavorings that can introduce soy, wheat, or fish. Ask the restaurant whether the steak is seasoned or marinated, and if so, what the ingredients are.
Yes, sesame can appear in two places: the sub roll (if it is a seeded bun) and the sauce (if tahini is used). Some Mediterranean restaurants use tahini in dressings or spreads. Ask the restaurant whether their roll is seeded and whether any sauces contain tahini. If both are sesame-free, the sub is likely safe for a sesame allergy.
