To make the dressing, add the garlic, yogurt,
parmesan,
mustard,
vinegar, anchovy paste, lemon juice, salt and pepper to a
food processor and blend until pureed. With the processor still on, stream in the
olive oil until a creamy dressing forms. (This will probably make more dressing than needed, but you can store it sealed in the
fridge for about 3 to 4 days and stir well before using.)
