For the amount of work involved, we prefer Cooking Light's Turkey Tetrazzini from Jan 2013. We did enjoy the Cauliflower Salad and will definitely be making that again. If it matters, I did use roasted chicken breast as the market didn't have roasted turkey today.
As stated, I didn't have the leftover cauliflower salad that the recipe called for, so I don't know if I had used it if it would have tasted better. I just used plain steamed some cauliflower and the dish was very bland, even after adding peas and a bit more cheese. It was a lot of work for it to turn out as bland as it was. If you have the cauliflower salad give it a shot, maybe it would be more flavorful. I am going to add some marsala to my leftovers, in hopes that it gives it a bit more depth.
