I remember eating Sunday lunch at my maternal grandparents' house. Fried chicken stands out as the meat of choice. She passed away when I was 11, and the tradition stopped there. My dad worked shift work, so our meals at home centered around what he worked. We were fed, of course, but we would have easy meals if he wasn't home.
For years, I fixed eggs, bacon/sausage for Sunday lunch because it kept me from having to come up with something more involved. It was quick, easy, and worked. Now, dh is only here every other weekend, ds is away at college. My lunch today was a big salad.
