Mustard Vinaigrette, ala Paris Bistro

Ingredients:
1 garlic clove, sliced in 1/2
1 teaspoon Dijon mustard
1 T balsamic vinegar
soy sauce, a splash (about 1 teaspoon)
salt and freshly ground black pepper
3 T olive oil

Preparing the dressing:
3 cups mixed greens, the darker the better

Rub the inside of a large wooden bowl with both halves of the garlic clove. Put the mustard in the bowl and whisk in the balsamic vinegar and soy sauce vigorously for about 10 seconds to get a creamy consistency. Season with salt and pepper, to taste. Drizzle in the olive oil slowly to emulsify. Place the salad greens on top of the dressing. Toss just before serving.
