You know, I think we should put in the years we're talking about. In my case it was the 60s. Dad was an Air Force sergeant with three daughters and one on the way. Mom helped the budget by taking care of other peoples' children. So the house was always, and I do mean always, full of children.
The reason I think that you need to tell what years we're talking about is that some foods aren't cheap now, that were then.
We ate so many dishes with ground beef you cannot imagine. One of my sisters hates ground beef to this very day. Daddy wasn't big on hamburgers. We'd eat spagetti with meat sauce, a casserole of hamburger layered with mashed potatoes and a can of creamed corn on top. When life was flush, mom would wrap a slice of bacon around a beef patty and we'd pretend it was "filet mignon". It was years before I had the real thing.
We ate a lot of chicken. Now we take for granted being able to get chicken parts that we like or don't. Mom would roast a chicken, or she'd prepare it and get dad to put it on what we (and everyone else we knew) called the barbecue pit. Mom would collect all of the chicken innerds and make a separate meal of them.
That meal was what I called Lizards and Gizzards. After a few chickens, Mom would pull the innards out of the freezer, boil them, then boil egg noodles in that broth, and toss in whatever veggies were on hand. I loved this meal.
While my sister hated ground beef, guess what? I hated hot dogs. And we had them in every form known to mankind.
On top of that, we were Catholic. Imagine, having to eat fish on Friday when it was pretty grotesque. Seriously, I love good fish, but many of the places we lived, good fish simply wasn't available. I hated fish, really hated it, until I was about 30 and had fish in Hawaii ... yes, I married a military man.
Hot dogs, hamburger (what we called ground beef then), and potatoes in every way, shape and form. Chicken ... not chicken breasts, the most over-rated piece of meat known to mankind, but entire chickens.
I don't think my younger sibs actually "get" the way we lived when I was a child. The food was good, but it was a lot of work for my mother, and I truly appreciate it now.
