Cauliflower - Cheese - Mashed. What are your thoughts on mashed veggies? From my standpoint, any veggie cooked and mashed is great. Beyond potatoes, I have to say that my favorite is mashed cauliflower.
Have you ever had mashed cauliflower? 
This is a great substitute for mashed potatoes. The texture is close, the color is the same. Plus, you get a couple of extra vegetable servings behind your belt for the day. You can make these in many different ways. My favorite is a puree of cauliflower with boursin cheese. I can't say that this is a fat free version, but it is absolutely wonderful. Tonight, we ate the last of the turkey from Christmas and I made mashed cauliflower with sour cream and herbs.
What are your mashed favorites? Are you willing to try things other than mashed potatoes?
