1/3 cup balsamic vinegar
1 tbsp. unsalted butter
1 tbsp. flour
1/3 cup chicken stock
1 lb. mortadella without pistachios, cut into 1/2″ cubes
1/3 cup heavy cream, whipped to soft peaks
2 loaves ciabatta, sliced
4 tbsp. extra-virgin olive oil
3 tbsp. crushed toasted pistachio nuts
1/2 cup baby arugula
Pour vinegar into a small saucepan and cook over medium heat until reduced to 3 tbsp., about 5 minutes; remove from heat and set aside. In a small saucepan, melt butter over medium heat. Whisk in flour and cook, whisking, for 1 minute. Slowly whisk in chicken stock and cook until thickened, about 2 minutes; remove velouté sauce from heat and set aside to let cool.
Put mortadella into a food processor and process until puréed. Transfer mortadella to a medium bowl. Using a rubber spatula, fold in the reserved velouté sauce and whipped cream; set aside. Rub the ciabatta with the oil and grill or toast. To serve, smear the grilled bread with the mortadella and garnish with a drizzle of the reduced balsamic and a scattering of pistachios and arugula. Serve warm or at room temperature.
