Wash clean potatoes, steam until tender but not too soft. Take out from steamer, soak in cold tap water, then quarter. Place in a large bowl

Wash radish and remove a little of the top and bottom, slice into smaller portions, then add into the bowl as well

Slice thinly green onion, also add into the bowl

Add enough mayonnaise as a binder but also as a flavoring, adjusting salt and black pepper to your liking and if you like to, lemon or lime juice as well

Serve with your favorite steak! (Serve immediately will still give you the crunching of radish, but chilled a couple of H before serving allows flavorings to distribute evenly)
