I'm not the cookie dough poster, but I've done it often. Almost any ordinary cookie recipe should be ok, like peanut butter, sugar cookies, chocolate chip. I've frozen them in "drop" form on cookie sheets and then bagged them, or made it into logs (like the Pillsbury refrigerated ones), wraped in plastic wrap and then in foil. I mostly to it that way, because it's much more space efficient, and it thaws quickly.
I don't usually freeze whole meals, but try to keep ingredients on hand for really quick throw-things-in-a-skillet dinners -- like pre-cooked chopped chicken and ground meat.
