Gina - I don't know if this is it but this IS a good one.....

Cook your potatoes until they are cooked through and then cube them.

Mix together miracle whip, a touch of lemon juice, some finely chopped onion,
chopped flat-leaf parsley (is it chinese parsley?), make sure this is all
blended well. You can grate the onion of you don;t like bits.

Pour over the potatoes while they are still warm and mix well.

Hope you like this!

My dad used to do a potato salad that was so easy - all he did was dress warm
cooked potatoes with lemon juice, parsley and a touch of olive oil. They tasted
great!
