As the subject of what variety of cheese on toast to have with tomato soup came up recently between me and another pup who remembers this as a childhood event, I’m throwing it to you.
When I was a child, we often had canned tomato soup, served with a slice of toast with cheese melted on it. This was called cheese toast, and probably was usually Velveeta. For our fellow pup, spudtruckowner, it was the same soup, but with his sandwich two pieces of bread, buttered on both sides, grilled on a flat griddle on the stove. His was a grilled cheese sandwich, and probably also made with Velveeta.
