Slice the mozzarella into squares, the bread into cubes (and toast them in the oven or toaster oven).
Skewer together the salami, bread, mortadella, capicoli, provolone, another piece of bread, and top with an olive. See notes.
Repeat that 10 times.
For the Vinegar Dressing
Add everything to a blender, blend it and drizzle over the skewers. Go light here. You can always use leftover dressing for salads or as a dip for the skewers.
Notes
You are more than welcome to measure with your heart. If you love cheese, feel free to add more. Want less mortadella, go right ahead. No capicoli? Use deli ham instead. Make this recipe work best for you.
Putting it together
For each skewer I used 3 salami, 3 slices of mozzarella, 1 mortadella, 2 capicoli, 1 provolone. I folded each piece 3 times before I added it to the skewer. The mozzarella was not folded, I cut it into squares as it was a stronger cheese that would break and not bend. Instead of adding olives to the skewers, I placed it in the center of the platter and added a few more spoonfuls of the muffuletta mix on top.
