A salad dressing is what can turn a good salad into a great salad. This dressing, which I veganized from Ken Charney's The Bold Vegetarian Chef, has both great flavor and is super quick.
1/4 cup extra virgin olive oil
2 tablespoons red wine vinegar
2 teaspoons agave syrup
2 teaspons white miso
Blend the ingredients together well with a whisk.
