French Potato Salad

I had some wonderful potato salad at a tea room in Hannibel, mo. This is my re-creation and it was a huge hit with the adults and kids in my house.

5 or 6 poatoes, peeled and chopped in bite sizes
1 jar Grey Poupon country Dijon (this must be specific, it's the main part of the recipe)
Salt

Boil the potatoes till fork tender, not mushy. Drain, put in a bowl, and mix with the mustard. You won't use the whole jar, start small and mix till the potatoes are lightly coated. Salt to taste and serve. Enjoy!
