looking for sbarro recipe

I use to live in Long Beach, CA while I went to college and I worked at Lakewood Mall in Lakewoods,CA. I use to order one of their side dishes that had string/green beans and herb potatoes. Can’t really remember too much more about it but I do remember it was very delicious. They do not make it by me in WI or MN. Please help with any info if you can. Thanks

it is red skin potato par-boiled mixed in a viningar and oil dressing with defrosted green beans added
try adding a little chopped red onion and grape tomatoes
