When we had something like this, which was rare-
very rare, it was the red box Stouffer's dishes. Ma was an excellent cook, but sometimes after a day of teaching Home Economics/Domestic Science, enough was enough. After our housekeeper retired, we had Stouffer's more often, but no more than once a week.
I can remember a small flirtation with Swanson dinners, but just a small one.
