The “Best Sandwich” She’d Ever Had
Before a month of testing summer recipes with my sister, I finalized this Ciabatta Sandwich. My sister tried it as soon as she arrived and immediately declared it the best sandwich she’d ever had. She’s since made it repeatedly for family and friends. The sandwich balances textures and flavors: warm ciabatta with a crisp edge, a creamy pesto-mayo spread, thin provolone, layers of ham and salami, bright quick-pickled onions, and dressed arugula. Each element supports the others, creating a sandwich that feels both indulgent and fresh.
I love how fast it comes together and how adaptable it is—swap meats and cheese as you prefer, or omit the onions if they’re not your thing. The pesto-mayo is two ingredients and lifts the whole sandwich, while the dressed arugula adds a refreshing contrast. This is a great recipe to bring to casual gatherings or to make when you want a very satisfying sandwich without fuss.
Ciabatta Sandwich Ingredients
| Ingredient | Notes |
|---|---|
| Ciabatta bread | Take-and-bake ciabatta yields warm, fresh bread. If using a standard loaf, gently toast it before assembling. |
| Mayo and pesto | Use a good-quality refrigerated pesto for brightness. Combine with mayonnaise for a creamy spread; this two-ingredient mix is quick and flavorful. |
| Provolone, deli ham, and salami | Ultra-thin provolone and thinly sliced deli meats provide the best texture and layer easily without overpowering the bread. |
| Quick-pickled red onions | Drain well before adding so the bread doesn’t get soggy. Add to taste or omit if you prefer no onions. |
| Arugula and dressing | Toss the arugula with a light dressing right before assembling so the greens stay crisp and flavorful. |
Chelsea’s Notes
What To Serve On The Side
This sandwich pairs well with many simple sides. A crisp green salad balances its richness, while kettle chips or fries add a satisfying crunch. For a picnic or potluck, a chilled pasta salad or a creamy cucumber salad are excellent choices. Fresh fruit or a mixed fruit salad keeps the meal light and refreshing. Classic pickles or fresh vegetable sticks with a dip are also great accompaniments.
- Simple green salad
- Kettle-cooked chips or fries
- Pasta salad or cucumber salad
- Fresh fruit or fruit salad
- Pickles and fresh veggies with dip
Storage
Make Ahead and Storage: Prepare the sandwich without adding the pesto-mayo, pickled onions, or dressed arugula. Wrap tightly and refrigerate for up to one day. Add the pesto-mayo, pickled onions, and dressed greens just before serving to keep the bread from becoming soggy.
For Beach or Pool Days: Pack components separately in a well-chilled cooler and assemble at your destination. This keeps everything fresh and prevents the sandwich from getting soggy.

Equipment
-
Wide-mouth mason jar or a small bowl with a whisk
Ingredients
- 1 (14-ounce) loaf ciabatta bread (adjust if your loaf is larger or smaller)
- 1/3 cup mayonnaise
- 1/3 cup refrigerated pesto
- 8 slices ultra-thin provolone cheese
- 10 slices deli ham (about 5 ounces)
- 15 slices deli salami (about 5 ounces)
- 4 lightly packed cups arugula
- Quick-pickled red onions, as desired (optional)
- 1/2 teaspoon Dijon-style mustard
- 1 tablespoon apple cider vinegar
- 1 tablespoon honey
- 2 tablespoons olive oil
- 1/8 teaspoon garlic powder
- Pinch of salt
Instructions
- Prepare the bread: If using take-and-bake ciabatta, bake according to package directions. If using a ready loaf, gently toast it in a toaster oven or under a broiler for a minute or two until lightly crisp. Let the bread cool briefly before assembling.
- Make the pesto-mayo spread: In a small bowl, whisk together the mayonnaise and pesto until smooth and evenly combined. Taste and add a touch more pesto or mayo if you prefer a stronger or creamier flavor.
- Dress the arugula: Combine the Dijon, apple cider vinegar, honey, olive oil, garlic powder, and a pinch of salt in a wide-mouth mason jar or small bowl. Shake or whisk vigorously until emulsified. Place the arugula in a large bowl and add just enough dressing to very lightly coat the leaves. Toss gently and use immediately—do not dress the greens far in advance.
- Slice the loaf: Place the ciabatta flat on a cutting board. Using a large serrated knife, slice horizontally through the center to create a top and bottom piece.
- Add spreads and cheese: Generously spread the pesto-mayo on both cut sides of the bread. Lay half of the provolone slices over the bottom half and the remaining slices over the top half so every bite includes cheese.
- Layer the sandwich: Over the bottom half, arrange 5 slices of ham and all of the salami. Add a thin layer of pickled red onions to taste, then pile the dressed arugula evenly over the meats. If desired, drizzle a little of the remaining dressing over the arugula. Add the remaining ham slices on top of the greens to help keep them in place.
- Finish and serve: Place the top half of the bread over the fillings and press gently to secure. Using a very sharp serrated knife, cut the loaf into 6 sandwiches. Serve immediately and enjoy the contrast of warm bread, creamy spread, tangy onions, and peppery greens.
Recipe Notes
Tip: Take-and-bake ciabatta gives the best warm, lightly crisp texture, but any ciabatta will work—just toast it lightly first if it’s already baked.
Pesto choice: A fresh refrigerated pesto makes a big difference. If possible, choose a pesto you enjoy or make your own. Shelf-stable pesto tends to be less bright in flavor.
Onion option: Quick-pickled red onions add tang and brightness; omit them if you’re not an onion fan. Make sure to drain them well so the bread stays crisp.
Make ahead: Assemble without the pesto-mayo, pickled onions, or dressed arugula and wrap tightly; refrigerate for up to one day. Add the remaining ingredients just before serving to maintain texture and freshness.
