On a Roll Sandwich Company-Style Italian Sub

This On a Roll Sandwich Company-style Italian sub layers sliced deli meats, provolone, crisp vegetables, and tangy dressing in a toasted roll. It is a generous, customizable deli sandwich, and keeping the dressing off the bread until assembly helps the roll stay pleasantly crisp.

Ingredients

4 sturdy Italian sub rolls, about 8 inches (20 cm) each
2 tablespoons (30 ml) extra-virgin olive oil
1 tablespoon (15 ml) red wine vinegar
½ teaspoon dried oregano (about 0.5 g)
¼ teaspoon fine salt (about 1.5 g)
⅛ teaspoon freshly ground black pepper (about 0.3 g)
8 ounces (225 g) thinly sliced provolone cheese
8 ounces (225 g) thinly sliced cooked turkey breast
6 ounces (170 g) thinly sliced cooked ham
6 ounces (170 g) thinly sliced salami
2 cups (80 g) shredded iceberg lettuce
1 medium tomato, thinly sliced (about 150 g)
½ small red onion, thinly sliced (about 50 g)
½ cup (60 g) sliced mild banana peppers, drained
¼ cup (35 g) sliced black olives, drained
2 tablespoons (30 g) mayonnaise, optional

Instructions

Heat the oven to 350°F (175°C). In a small bowl, whisk the olive oil, red wine vinegar, oregano, salt, and pepper. Set aside. Shred the lettuce, slice the tomato and onion, and drain the peppers and olives well.
Split the rolls lengthwise, keeping one long edge attached if you like a hinged sandwich. Arrange them cut-side up on a baking sheet. Toast in the oven for 4–5 minutes, just until warmed and lightly crisp at the edges. Do not let them become hard or brittle.
If using mayonnaise, spread a thin layer over the cut sides of the rolls. Divide the provolone among the rolls, then layer on the turkey, ham, and salami. Fold the meat loosely rather than pressing it flat; the layers make the sandwiches easier to bite.
Add the tomato, red onion, banana peppers, and olives. Spoon the oil-and-vinegar dressing over the vegetables and meat, using about 1½ teaspoons per sandwich to start. Add more to taste, but avoid flooding the bread. Finish with shredded lettuce.
Close each roll gently, cut in half if desired, and serve right away. For a neater packed sandwich, wrap it snugly in parchment or sandwich paper and cut through the paper.

Tips

Keep the bread from getting soggy: Drain wet toppings thoroughly, toast the rolls briefly, and put lettuce between the wetter vegetables and the bread. Dress just before serving.
Choose the right roll: A soft but sturdy Italian roll is easiest to eat. If yours is very crusty, warm it rather than toasting it further; if it is soft, a short toast helps it support the fillings.
Adjust the salt thoughtfully: Deli meats, provolone, olives, and peppers can all be salty. Taste a small bite before adding extra salt to the dressing.
Make components ahead, not assembled sandwiches: Slice the vegetables and mix the dressing up to a day ahead, storing them separately in the refrigerator. Assemble shortly before eating for the best texture.

Serving Suggestions

Serve the subs with kettle-style potato chips, a simple green salad, or a cup of vegetable soup. For a deli-style spread, offer extra banana peppers, pickles, and dressing at the table so everyone can adjust the tang and crunch. These substantial sandwiches can be served whole for a hearty lunch or cut into smaller pieces for a casual gathering.

Variations

Make it spicy: Replace mild banana peppers with hot cherry peppers or add a few thin rings of pickled jalapeño. Their brine will add both heat and acidity, so begin with a small amount.

Use different deli meats: Swap the turkey for roast beef or replace the ham with extra turkey. Choose cooked, ready-to-eat deli meat, and keep it refrigerated until assembly. For a meat-free version, use grilled vegetables such as zucchini and bell pepper with extra provolone or a firm cheese of your choice.

Change the cheese: Mozzarella gives a milder, softer flavor; sharp provolone makes the sandwich more assertive. If using fresh mozzarella, pat it dry and use it sparingly because its moisture can soften the roll.

Make a pressed sub: Assemble without the lettuce, wrap the sandwich in foil, and warm it in a 350°F (175°C) oven for about 8–10 minutes, until heated through. Add the lettuce afterward so it stays crisp. The texture will be softer and more like a warm deli sandwich.

Storage and Reheating

For best quality, assemble only as many sandwiches as you expect to eat. Refrigerate sliced deli meats and any assembled leftovers within 2 hours; if the room is above 90°F (32°C), refrigerate within 1 hour. Keep leftover components in separate airtight containers. Cooked deli meats and cut vegetables are generally best used within 3–4 days when held at 40°F (4°C) or colder, though package dates and instructions may call for earlier use.

An assembled sandwich can be refrigerated for up to 1 day, but the bread and lettuce will soften. Remove cold toppings and lettuce before reheating, wrap the meat-and-cheese portion in foil, and warm in a 350°F (175°C) oven until the center reaches 165°F (74°C), the USDA FSIS safe temperature for reheated leftovers. Add fresh lettuce after warming. Do not leave the sandwich at room temperature for more than 2 hours.

Frequently Asked Questions

What is an On a Roll Sandwich Company-style sandwich?
This recipe is a deli-inspired Italian sub with sliced turkey, ham, salami, provolone, vegetables, and an oil-and-vinegar dressing. It is a home version rather than a claim to reproduce a particular shop’s exact recipe.

Can I make these sandwiches ahead?
Prepare the dressing and slice the vegetables up to a day in advance, storing each separately in the refrigerator. Toast and assemble the rolls shortly before serving; preassembled sandwiches lose their crisp texture as the vegetables and dressing sit against the bread.

What can I use instead of banana peppers?
Use sliced pepperoncini, mild pickled peppers, or a few pickle slices. Pepperoncini are similarly tangy, while pickles bring a more pronounced cucumber flavor. Drain any substitute well before adding it.

Do I have to toast the rolls?
No. Toasting is optional, but a brief warm-up firms the cut surface and makes the rolls less likely to absorb dressing quickly. Skip it if you prefer a soft, traditional cold sub.

How do I keep the sandwich from falling apart?
Use a roll that is sturdy enough for the fillings, avoid overfilling, and drain the vegetables. Layer cheese and meat first, then add vegetables, and wrap the sandwich tightly if you are carrying it.

Can I freeze an assembled sub?
Freezing is not recommended: lettuce, tomato, and the roll become watery or mushy after thawing. Freeze only suitable unopened deli meat according to its package directions, then thaw it safely in the refrigerator and assemble a fresh sandwich.
