Braised Leeks with Vinaigrette

A classic French bistro preparation that transforms whole leeks into a tender, luxurious side dish by braising them in broth until silky-soft, then dressing them with a sharp mustard vinaigrette while still warm. The leeks soak up the vinaigrette as they cool. Serve warm or at room temperature as a starter or alongside grilled fish or chicken.
