Even if you don’t want to make it, I’ve never been in a supermarket that doesn’t offer a fresher option. I’ve even been in gas stations that offer what they at least claim is fresh potato salad.
Maybe if you really, really wanted potato salad and you were in a food desert but the corner 7-11 has canned potato salad you might buy it, but I’ve never seen this before in my life.
I don’t get it.
I could definitely see something like that, although I think you’d probably get something that tasted better with a blended potato soup and there’s a bunch of canned varieties. I suppose if someone like that is jonesing for some potato salad (I wouldn’t blame them, potato salad is great), this is the best way to give it to them.
