This really wasn't bad...I'm not a huge fan of green beans but this is one of the tastier ways I've found to prepare them. I didn't have wax beans so the proportion of potatoes was increased, although it still seemed small. I also fudged the amounts with the dressing but the combination of flavors was good - I expected it to need sugar to take the edge off the vinegar but it didn't. This is a nice change from boring potato salad so I'll keep this in mind in the future.
Sooooo good! Family loved it. My only question is why return the potatoes to the pot with vinegar? They got a little overcooked and smashed a little. Otherwise this will be a go-to recipe for us!
Served this at a dinner party - was great to be able to make ahead and have at room temp! The guests loved it and we will definitely do it again. Very flavorful.
