Preheat oven to broil. Line a broiling pan with aluminum foil; set aside.
Thinly spread one side of salmon with one-third of the pesto. Squeeze lime juice over salmon and lightly season with pepper to taste.
Lay salmon on broiler pan pesto-side down. Broil for 6 to 8 minutes or until fish flakes easily with a fork. Remove from oven. Spread remaining pesto generously on salmon and serve immediately.
