Wild Rice and Brown Rice Salad with Walnut Vinaigrette and Asparagus

Nice concept, but the recipe has a couple problems. The salad is pretty simple - a couple types of rice, some lightly steamed asparagus, herbs, walnuts, and a dressing. I prepared as described, except I doubled the asparagus.

The dressing called for 1/2 C of oil, and as I was adding it, I became skeptical. I added ~2/3 of the dressing, and the salad felt quite greasy. I didn't care for the dressing on the day I prepared this, but as leftovers for my lunch, the flavors had melded, and it was better.
