Thanks for posting this recipe. It was exactly what I was looking for, and the two of us enjoyed it immensely. There was nothing to change, really, except I used a new crop apple - Sunrise - which wasn't as tart as Granny Smith but still terrific. My compliments to you, Luby.
Now that I've tried this recipe, which at first I didn't think that I'd enjoy, I find myself craving it. I love the candied effect that the walnuts take on, it's such a great treat. I added a few things to the vinaigrette like minced garlic, and an egg white. I heard of one of my favorite Italian resturants does that with their house vinaigrette. I love love love this salad
