Those ingredients are very close to my Watergate Salad recipe, but I’ve never added cherries to mine.
Also, I use pistachio pudding mix, but it’s probably pudding and pie filling mix.
I’ve never put pistachios in mine because I use pecans but it probably doesn’t matter as long as it’s a little nutty. :-D
I think sometimes cherries are used as a garnish.
Watergate?
