I love comfort food, but my husband likes more exotic flavors. So this is a compromise that I came up with recently. It satisfied my craving for something warm and belly-filling while tempting his adventurous palate. This recipe improvises upon three recipes I found here, numbers 100215, 10744 and 51269. You can substitute carrots and cauliflower for the sweet potatoes and parsnips, respectively. I prefer the Bisquick crust, but puff pastry and regular pie crust would also work well.
