How to Make It
Fill a saucepan with enough water to cover the salmon. Add bay leaf and simmer until just cooked through, 8 to 10 minutes; remove and flake. Meanwhile, cook penne according to the package directions. In a large skillet, toast pine nuts over low heat until golden, 3 minutes; remove from pan. In the same skillet, heat olive oil. Add the penne, salmon, lemon juice, and kosher salt and cook until heated through, 2 minutes. Stir in arugula and fresh chives.
