Place all the ingredients for the dressing in a tall glass jar and mix with a stick blender until well blended and slightly emulsified, about one minute. If you don’t have a stick blender, you could also use a small food processor. Set aside.
Bring about an inch of salted water to a boil. Place the beans in a steaming basket and set over the boiling water. Cover and steam until tender to the bite, 3 to 5 minutes (depending on how crisp or tender you like them)
As soon as beans are ready, plunge them in a bowl of icy cold water to stop the cooking, then drain, pat dry and divide them between two serving plates
Divide the rest of the ingredients between the 2 plates and arrange them so that they look pretty. Serve with Honey-Dijon Vinaigrette.
