1In medium saucepan bring broth to a boil. Stir in couscous. Cover pan and remove from heat. Let stand 10 minutes until liquid is absorbed. Fluff couscous with a fork, then toss with 1/3 cup of the vinaigrette.
2To assemble, place couscous in the center of a large platter. Arrange artichoke hearts, tomatoes, olives and chicken (tuna or anchovies); separately but surrounding the couscous. Drizzle the remaining vinaigrette over the plattered items.
31/3 cup sliced green onions or 2 TBS chopped fresh mint can be tossed into the couscous, before plating it on the platter.
