RECIPE IDEA: Balsamic Vinaigrette, delicious on grilled vegetables, salad or chicken. Hi. It's Lois in the kitchen at Recipe Idea Shop. We had some beautiful Portobello mushrooms and decided to grill them with a Balsamic Vinaigrette. They were super yum! This dressing is terrific on a salad or as a marinade for vegetables, meat or chicken.
