Stir together goat cheese and pesto. Spread goat cheese-and-pesto mixture on cut sides of rolls. Layer pork roast, arugula, and remaining ingredients on bottom halves of rolls. Cover with top halves of rolls.
*1 lb. thinly sliced Slow-Cooker Pork Butt Roast may be substituted.
Note: For testing purposes only we used Buitoni Pesto With Basil and Cobblestone Mill Ciabatta Rolls.
