Step 1

In a small bowl combine the pesto, olive oil, vinegar, garlic, sugar, salt, and pepper and whisk until smooth. Taste and add additional salt and pepper if needed. Set aside.

Step 2

Lay the bread cut side up on a cutting board. Gut the top piece of ciabatta by pulling out some of the inside bread, which will create ample space for the filling. Lightly brush both cut sides of the bread with the pesto vinaigrette.

Step 3

Layer the turkey, prosciutto, provolone, sun-dried tomatoes, and arugula on the bottom half of the ciabatta. Drizzle the top of the arugula generously with the vinaigrette. Add the top half of the ciabatta and gently push down on the sandwich.

Step 4

Slice the sandwich into 4 to 6 pieces, secure pieces with a toothpick, place on a platter, and serve.
