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 glass or plastic dish; mix well. Add salmon, skin side up. Cover; refrigerate 30 minutes.

Cook 4 to 8 minutes or until flesh is opaque and flakes easily with fork.
