I thought this might be a helpful site.  It has several mixes that you can
make out of ingredients that you can make sure are gluten free.

These are the dry mixes so all you have to do is add a few ingredients to
put them together for a quick dessert, salad dressing or meal.  They are
handy to have on hand.
