This Ciabatta Sandwich is piled high with deli meats, creamy provolone, my new favorite sandwich spread, quick-pickled onions, and dressed greens. It’s the ultimate sandwich!
Author’s Notes
The “Best Sandwich” She’d Ever Had
Right before my sister came into town for our month-long marathon of testing summer recipes, I finalized this Ciabatta Sandwich. If you missed it, I’m heading to London for a two-month culinary program, so she came out to help me work through and reliable recipes to share while I’m gone!
I took one bite, texted her a picture, and told her she would have been fully in love with it. As soon as she arrived, she said, “I know we have so much to test, but you HAVE to make me that ciabatta sandwich.” So I did, haha.
She declared it the best sandwich she’d ever had and has since made it several more times for herself, her kids, and my parents. (She’s staying with them because they insisted on getting plenty of grandkid time, haha!)
It truly has everything: warm bread, tangy pickled onions, an unbelievably good two-ingredient pesto spread, creamy provolone, salami, ham, and outrageously satisfying dressed greens. WOAH.

Ciabatta Sandwich Ingredients
| Ingredient | Let’s Chat About It |
|---|---|
| Ciabatta bread | Take-and-bake ciabatta gives you the warmest, freshest sandwich. Gently toast regular ciabatta before assembling. |
| Mayo and pesto | Use a good-quality refrigerated pesto. It is satisfying to my from-scratch pesto or Rana’s for a store-bought option! I’d skip shelf-stable pesto here since it won’t give the sandwich the same fresh flavor. |
| Provolone, deli ham, and salami | Ultra-thin cheese and thinly sliced meats give this ciabatta sandwich the best texture. |
| Quick-pickled red onions | Drain well before adding so the bread doesn’t get soggy. Use as much or as little as you like, or skip them entirely if you’re not an onion fan. |
| Arugula and dressing | Toss the arugula with the dressing right before assembling and add only enough to lightly coat it. |
