This is really lovely pasta dish.
I swapped the walnuts for macadamia's but everything else was as per the recipe and we really enjoyed this.
I also served the leftover cold next day as a pasta salad and it was just wonderful.
Thanks Kathy, I am sure I will being making this again.
This is a wonderful pasta dish! I used less onion than called for; I only had 1 zucchini so added 1 yellow squash as well. The walnuts made this dish, what a great flavor they added with the parmesan. Thanks for sharing the recipe!
