Vinaigrettes are interesting creatures. They are, of course, wonderful on salads, but can be used as quick marinades for grilling or broiling, and can dress up plain steamed vegetables in a heart beat. They're also nice for dipping crudite vegetables instead of more traditional creamy dips.
We like ethnic flavors at my house, so I make sure that amongst the many options for dressing our salads we have something representing the Mediterranean region and Southwestern cuisine now and again. Balsamic Vinaigrette and
Sun Dried Tomato, Chipotle and Cumin Vinaigrette are visitors to my table that are consistent hits with guests and family alike.
Looking towards the East we have Carrot Miso Dressing and Sesame Ginger Dressing. The latter also doubles as a quick marinade for fish, chicken or tofu.
