The chickpeas are toasted in the pancetta fat, which gives them a rich flavor.
1 red bell pepper
2 tablespoons extra-virgin olive oil
5 ounces pancetta, sliced 1/4 inch thick and cut into thin strips
1 cup canned chickpeas—drained, rinsed and patted dry (about 9 ounces)
2 tablespoons Prosecco
2 tablespoons white wine vinegar
1 large garlic clove, minced
Salt and freshly ground pepper
2 medium heads radicchio (3/4 pound), coarsely chopped
2 bunches arugula (3/4 pound), coarsely chopped
3 ounces aged provolone cheese, cut into thin shavings
Preheat the broiler. Roast the bell pepper under the broiler or over an open flame, turning, until charred all over. Transfer the pepper to a bowl, cover with a plate and let steam for 5 minutes. Peel, seed and core the pepper and cut it into 1/2-inch dice.
In a large skillet, heat 1 tablespoon of the olive oil. Add the pancetta and cook over low heat, stirring, until lightly browned, about 8 minutes. Using a slotted spoon, transfer the pancetta to a plate. Add half the chickpeas to the skillet and cook over moderately high heat, shaking the skillet, until the chickpeas are lightly browned and slightly crisp, 3 to 4 minutes; transfer to a plate. Repeat with the remaining chickpeas.
In a small bowl, combine the Prosecco with the vinegar, garlic and the remaining 1 tablespoon of olive oil. Season with salt and pepper.
Preheat the oven to 400°. Return the pancetta and chickpeas to the skillet and rewarm them in the oven for 3 minutes. In a large bowl, toss the radicchio with the arugula, provolone, pancetta, chickpeas and roasted red pepper. Add the dressing, toss well and serve at once.
The salad and Prosecco dressing can be prepared through Step 3 up to 4 hours ahead.
A round, mouth-filling Spumante softens the sharp flavors of the provolone and bitter greens in this salad, while its effervescence lightens the texture of the chickpeas.
