Have to believe it was a generational thing. In the 50's, jello must have been the greatest invention since sliced bread to my mother. I remember some combinations like shredded carrots and fruit together in jello. Maybe referred to as "Aspic". Sometimes mayonnaise spread on top of these so-called molded creations. I HATED it. Don't remember raw veggies used in much of anything back then. The occasional relish tray of pickles, olives, carrots and celery. A simple tossed salad. Coleslaw that I'd gag on. Sometimes a leaf or two of iceberg lettuce with a slice of tomato on it. No doubt there wasn't the abundance and choice you'd find in a grocery now.
