Leeks Vinaigrette

1 bunch leeks
2 tsp red wine vinegar (or vinegar of choice)
½ tsp Dijon mustard
Salt and pepper to taste
1 Tbls olive oil
½ Tbls chopped fresh parsley (or other fresh herb)

Cut leaves off leeks, and slit halfway through each leek starting from green end, stopping 2 inches shy of the white end. Rinse in a bowl of water to clean. Add leeks to a pot of boiling salted water (5 cups water, 1 tsp salt) and simmer until tender, about 10 min. Drain. In a small bowl, whisk together vinegar, mustard, salt and pepper, olive oil and parsley. Drizzle over leeks. Serves 2-4.
