Yield Serves 10 to 12

Ingredients
    3 red bell peppers (about 1 pound)
    One 6-inch pita bread (2 ounces)
    1 cup water
    1 small garlic clove
    4 ounces walnut (about 3/4 cup) toasted plus more for garnish
    1 1/2 teaspoons paprika, plus more for garnish (optional)
    3/4 teaspoon ground cumin
    1 tablespoon balsamic vinegar
    1 tablespoon freshly squeezed lemon juice
    2 teaspoons extra-virgin olive oil, plus more for drizzling
    3/4 teaspoon coarse salt
    Freshly ground black pepper

Method
Roast peppers over a gas burner until blackened all over, turning with tongs as each side is blistered. (Alternatively, place under a broiler.) Transfer to a bowl, and cover with plastic wrap; let stand about 15 minutes. Peel, and discard skins, stems, and seeds. Set peppers aside.
   
Toast pita bread until crisp and golden. Break into 2-inch pieces; place in a bowl, and cover with the water. Soak until soft, about 10 minutes. Transfer to a sieve, and drain well, pressing out excess water. Set aside.
   
Combine garlic and walnut pieces in the bowl of a food processor; process until fine crumbs form, about 10 seconds. Add paprika, cumin, and reserved peppers and pita bread; process until smooth, about 10 seconds. Add vinegar, lemon juice, oil, and salt, and season with black pepper. Pulse until combined.
   
Transfer to a serving bowl; cover with plastic wrap. Refrigerate at least 1 hour or overnight. Before serving, bring to room temperature. Drizzle with oil; sprinkle with walnuts or paprika, as desired.
