Soak cedar plank or shingle in water 1 to 2 hours. Combine all relish ingredients in medium saucepan. Cook over medium heat until mixture boils, stirring occasionally. Reduce heat; simmer 6 to 8 minutes or until onion is tender and mixture thickens. Cool. Meanwhile, combine soy sauce, orange juice and honey in shallow dish; add salmon, skin side up. Cover; refrigerate 30 minutes. Heat grill to medium high. Place salmon skin side down on plank; place on grill. Grill for 20 to 30 minutes or until flesh is opaque and flakes easily with fork. Place salmon on serving platter and cut into 4 pieces. Serve with relish. Makes 4 servings. TIP: Planks can be used several times if soaked well and used over indirect heat. After use, rinse plank well with warm water. Use scrub brush if needed.
