Shallot Vinaigrette
From Gourmet March 2001
1/4 cup finely chopped shallot
1 tablespoon Dijon mustard
2 tablespoons red-wine vinegar
1/3 cup olive oil (preferably French) or safflower oil
Whisk together shallot, mustard, and vinegar. Add oil in a slow stream, whisking until emulsified, and season with salt and pepper. Just before serving, toss salad greens with just enough dressing to coat.
