I had a bunch of leftover homemade basil/cilantro/almond pesto that needed to be used up as well as a craving for a salad. Did some Googling and came up with this creamy pesto parmesan salad dressing recipe that looked pretty good. Apparently it's based on a well-loved and much sought-after recipe from the Old Spaghetti Factory. I've never been to that restaurant, but the dressing sounded pretty nice.
I put my own twist on it as follows, upping the pesto quantity and subbing in yogurt for the sour cream. I like how it turned out- tangy, herby and a hint of cheesey.
