Heat grill to medium-high. Rub 4 skinless salmon fillets (6 ounces each) with 1 teaspoon olive oil. Sprinkle with 1/2 teaspoon ground coriander; season with coarse salt and ground pepper.
Lightly oil grates; place salmon, skinned side up, on grill. Cover grill; cook 5 minutes. Turn fillets; cover, and cook until opaque throughout and flaky, about 4 minutes more. Serve salmon drizzled with Citrus Sauce.
