Cook the pearl couscous according to the package instructions. Drain and set aside.
In a large bowl, combine the cooked couscous, parsley, dill, chives, lemon zest, lemon juice, and 1 tablespoon of olive oil. Season with salt and pepper to taste.
Season the salmon fillets with salt and pepper.
Heat the remaining 1 tablespoon of olive oil in a skillet over medium heat. Add the salmon and cook for 3-4 minutes per side, or until golden and cooked through.
Serve the salmon on top of the herbed couscous and garnish with extra herbs or a wedge of lemon if desired.
