Very close to what is used at Cafe Express on their Smoked Turkey Cobb Salad.
I agree (has potential). This is a good base for a "diet" salad dressing but you have to use some imagination with it. For instance, I like the Dijon mustard recipe but add honey instead of sugar. I love the cumin-lime one (especially with avocado) but also add a little lime zest and chopped cilantro, neither of which adds any real calories, and without the sugar. I wonder how green peppercorns would be with enough plain yogurt to make it creamy?
Skip the vegetable broth. Potential with a seasoned rice vinegar or balsamic vinegar. I'd also half the sugar.
