Below you’ll find an easy, practical recipe with tips, substitutions, and storage notes to make serving a crowd effortless.
This sandwich takes the classic Italian party sub and upgrades it with extra layers of texture and flavor: creamy provolone, tender mortadella, spicy soppressata, salty prosciutto, and briny pepperoncini, all brightened by peppery arugula tossed in olive oil. The Calabrian chili mayo adds a slow, smoky heat that plays well with the herbal pesto—together they keep every bite interesting. Make it a few hours ahead and the ingredients will settle into a single, perfectly cohesive sandwich that slices cleanly for easy serving.

Ingredients
- 3 tablespoons mayonnaise
- 1 tablespoon Dijon mustard
- 1 tablespoon jarred chopped Calabrian chili peppers (adjust to taste)
- 2 ciabatta loaves (10–12 inches each)
- 3/4 cup basil pesto
- 4 cups baby arugula
- 2 tablespoons extra virgin olive oil
- Freshly ground black pepper, to taste
- 10 ounces (about 12 slices) provolone cheese, divided
- 8 ounces thinly sliced mortadella, divided

Step-by-Step Instructions
1. Make the Calabrian chili mayo
In a small bowl, whisk together mayonnaise, Dijon mustard, and jarred chopped Calabrian chilies until smooth and evenly combined. Taste and adjust the chilies for more or less heat. Cover and refrigerate until ready to use; this sauce can be made up to 3 days ahead and will deepen in flavor as it rests.
2. Prepare the ciabatta
Using a serrated knife, slice each ciabatta loaf in half horizontally. Spread the basil pesto generously across the cut side of both bottom halves. Spread the Calabrian chili mayo across the cut side of both top halves—this creates a flavorful barrier that keeps the bread from getting soggy while adding a spicy, creamy element to each bite.
3. Dress the arugula
In a medium bowl, toss the baby arugula with the extra virgin olive oil and a few grinds of freshly ground black pepper. The light dressing softens the arugula slightly and helps it cling to the meat and cheese layers.
4. Layer the meats and cheese
On the pesto-lined bottom halves, arrange the fillings in this order for even distribution and visual appeal: provolone, mortadella, Genoa salami, hot soppressata, prosciutto, and pepperoncini. Overlap slices as needed to build consistent layers. Finish each sandwich by piling the dressed arugula on top of the meats.
5. Rest the sandwiches
Close each sandwich with the top ciabatta half (mayo-side down) and press firmly to compress the layers. Wrap tightly in parchment and then foil, and refrigerate for at least 30 minutes—up to 4 hours is ideal. Resting lets the flavors marry and helps the sandwich hold together when sliced.
6. Slice and serve
Unwrap and use a serrated knife to slice each loaf into 12 even small squares. Secure each square with a toothpick if desired, and keep them chilled in an airtight container or cooler until serving. These bite-sized pieces are perfect for parties, picnics, or game day trays.
Recipe FAQs
The Calabrian chilies bring a noticeable, lingering heat to the mayo. If you prefer milder flavor, reduce the amount of chopped Calabrian chilies or choose a mild soppressata instead of the hot variety.
You can let the sandwiches sit at room temperature for up to two hours for serving. For longer outdoor events or travel, keep them chilled in a cooler for food safety and best texture.
Focaccia (plain olive oil and sea salt) is a great substitute. Choose a neutral-style bread that will hold up to slicing and stacking.
Yes. The Calabrian chili mayo keeps in an airtight container in the refrigerator for up to three days and often develops deeper flavor overnight.

Tips, Variations, and Serving Ideas
- Make the chili mayo and prep the arugula ahead to speed assembly. The sandwich benefits from at least 30 minutes of chilling so flavors can meld.
- Swap or add cheeses—fresh mozzarella or fontina work well—or use a mix of mild and sharp provolone for contrast.
- For less sodium, trim portion sizes of cured meats or substitute with roasted turkey or chicken for a lighter option.
- Serve on a platter with pickles, olives, or extra pepperoncini on the side for guests to customize their bites.
- Keep extra sandwiches wrapped and chilled until just before serving to preserve texture and safety.
