I recall when TV dinners were on sale 10 for a buck at Great Scot back in the mid 60’s...and don’t get me started on those Banquet Cookin’ Bags, loved the turkey and gravy (over rice!)...
I do remember when they were very inexpensive. We ate a bunch of them as newlyweds. I had a lot to learn in the cooking department. :)
The cooking bags sound really good!
