Preheat broiler. Combine first 9 ingredients in a food processor; pulse 3 times or until coarsely chopped. Place fish on a broiler pan with cooking spray; spread 1/2 cup shallot mixture evenly over fish. Broil 15 minutes or until fish flakes easily when tested with a fork. Serve the fish with the remaining shallot mixture, and garnish with cilantro sprigs and lemon wedges, if desired.
