No. Growing up, our traditional Sunday dinner was hamburgers on the grill after Mass. (We went to 6pm folk Mass.)
Now, after church we go out to eat (ours is in the morning) and then dinner is a normal dinner. But, as the last poster said, one person's Sunday dinner might be somebody else's regular fare. Some people say I do a spread every night, but I just try to have a variety with lots of veggies.
