We do various things with it, but one of my favorites is to make turkey stuffing with it. I don't have the recipe here, but you just cook a cup (pre-cooking) of quinoa, preferably in stock. While that's going, sautee a chopped onion and celery. At the end, toss in some sage and whatever other seasonings float your boat, mix in the quinoa, put it in an uncovered baking dish and bake at 350° until the top is crispy.
We do this because my son is allergic to wheat, but I think I like it better than traditional bread-based stuffings.
