Mixed Greens and Fruit Salad with Warm Onion Vinaigrette

Heat 1 tablespoon of the oil in a 2-quart saucepan over medium heat. Add the onion and cook for 3 minutes or until it's tender. 2 Stir the broth, vinegar, brown sugar and mustard in the saucepan and heat to a boil. Cook for 5 minutes or until the mixture is slightly reduced. Remove the saucepan from the heat. Beat the remaining oil into the broth mixture with a fork or whisk. 3 Toss the salad greens with 1/2 cup dressing in a large bowl. Arrange the greens on a serving platter. Top with the pears, cherries, pecans and cheese, if desired. Serve with the remaining dressing.
