This post in another thread reminded me of a “salad” my mother used to make featuring cubed Velveeta and green olives. I think it might have been a pasta salad, but don’t honestly remmber. It was definitely served cold, not hot. I was born in 1974, and I know it was a common potluck item when I was a kid.
Fresh peas, and some kind of tangy dressing I think. I remember eating it at times. Sometimes it had other cheese cubes instead of Velveeta. Weren’t there some variations with mint and peas, and others that were almost ranchy in flavor, with bacon? I remember it had spiral pasta too.
The recipe on this page is the closest to the most common version that I ate, just add the cheese cubes. (Except I distinctly remember fresh/thawed peas with the one I ate most often, and onions, and sometimes other veggies, but peas definitely.)
