This stunning presentation of glistening vegetables is great on the buffet. Immediately after roasting, arrange the hot vegetables on a platter. Add olives and jarred marinated artichoke hearts, if you like. Serve the sauce in a bowl on the side, a basket of sliced French bread, and provide plates and forks. Or, if you prefer, serve the vegetables as a lovely side dish for one of your holiday meals.
