Two of my sisters and a neice are celiacs, meaning they can't have glutens either. I always try to make some foods/desserts whenever we have a family thing.
One favorite is Chicken Cutlet Parm, South Beach Diet style:
Take partially frozen chicken cutlets, trim fat.
In a large baking dish, spread out your favorite tomato sauce on the bottom of pan (homemade or canned - I personally love the DelMonte Traditional Sauce in the can for this particular recipe). Next, place the cutlets on top of the sauce and sprinle generously with shredded mozzarella cheese. Cover and bake at 350F for about 25 minutes, remove cover and continue baking till the top is melted and slightly browned. I serve this with a HUGE salad, and breads (italian for non=celiacs and gluten free for celiacs).
Another favorite is making gluten free pasta Baked Ziti - the trick is to undercook the rice pasta so it doesn't get all mushy. Also very yummy.
And for dessert, we usually whip up a batch of chocolate meringue cookies or non-flour chocolate cake or non-flour peanut butter cookies. The meringues are a big hit.
I once also made a 'carvel' cake using gluten free cookies. I crumbled them up and semi-defrosted the ice creams. In a casserole dish, first you spread some ice cream, then layer the crumbled cookies and then the last layer of ice cream and then deep freeze to harden. It serves just like the carvel cakes once decorated and everyone loves it.
