warm dijon potato salad with green beans

I regret that I don't have a picture of this really, really great potato salad. We made it for Memorial Day weekend to go with ribs. I couldn't get my camera out fast enough... but try it, its delicious.. and its great cold too. Thanks again and again and again Aubrey.. I wonder why I gain weight when I visit you...

3 pounds Yukon or baby white potatoes
1 pound green beans, trimmed
1/2 cup mayonnaise
2 tablespoons whole grain Dijon mustard
1 shallot minced
3 tablespoons red wine vinegar
30 grinds black pepper
1/3 cup packed finely chopped flat-leaf parsley
Directions
Place the potatoes in a large pot and cover with cold water by at least a couple inches. Salt the water generously, bring to a boil and cook until the potatoes are fork tender, about 20 minutes. Drain and rinse under cold water.
Bring another pot of salted water to a boil and throw the beans in just for a minute or two until they turn bright green. Strain them and run them under cold water to stop the beans from cooking.
In a mixing bowl combine the remaining ingredients and whisk until smooth.
Cut the potatoes in half lengthwise and then into roughly 1 inch chunks. Cut beans in half. Toss the potato chunks in the dressing and then toss in the green beans and the parsley.
