Mashed Potato Cauliflower Casserole

Mashed Potato Cauliflower Casserole is loaded with all the savory comfort flavors of "real" mashed potatoes but with more of the good-for-you foods and less of the not so good for you stuff. It's a one-pot, gluten-free side that is welcome at both holiday tables and as a base to a savory stew.
