This Potato Green Bean Salad is incredibly flavorful, thanks to a light and tangy Greek yogurt dressing, fresh green herbs and grain mustard.
In a small bowl, stir together the yogurt, lemon juice, lemon zest and mustard. Slowly whisk in the olive oil. Season to taste with salt and pepper.
I like to reserve some of the fresh herbs and grain mustard that get mixed in for garnishes. That extra sprinkle of herbs and tiny dollops of grain mustard go a long way, presentation wise.
