How to Make It
Fill a saucepan with enough water to cover the salmon. Add the bay leaf.
Simmer the salmon until just cooked through, 8 to 10 minutes. Remove from the pan and flake.
Meanwhile, cook the pasta according to the package directions.
In a large skillet, toast the pine nuts over low heat until golden, 3 minutes. Transfer to a bowl.
Heat the oil in the skillet over medium heat. Add the penne, salmon, lemon juice, and ½ teaspoon salt and cook until heated through, 2 minutes.
Stir in the arugula and chives.
