Preheat the oven to 350F and line a baking try with parchment paper.
Cut the Ciabatta Rolls into 1-inch cubes. Place the cubes on the prepared tray.
Drizzle the olive oil over the cubes of bread. Season with the salt and pepper.
Place in the preheated oven and bake for 10-15 minutes or until lightly golden.
Assemble the Salad
Place the prepared onion, tomatoes, bocconcini balls, olives, and basil in a large bowl (which can also take on the croutons). If you want to add the peperoncini, slice them up and add them too.
In a small bowl, whisk the ingredients for the salad dressing, and then drizzle over the salad ingredients. Toss everything to combine.
Allow for the croutons to come to room temperature. Place in the bowl with the rest of the ingredient and fold everything together.

Notes
Bonus Item: Prosciutto Chips
Lay your desired slices of prosciutto pieces, flat on a parchment lined baking tray.
Place the tray in the 350F oven, at the same time as the croutons.
The prosciutto slices should crisp up after 10-15 minutes.
Remove from the oven and transfer the prosciutto chips to a cooling rack. They will crisp up even more as they cool down.
Once cooled, break some up into the Crouton Salad or serve them whole on the side.
