In a medium bowl, add yogurt, Parmesan cheese, lemon juice, anchovy paste, garlic, salt and pepper. Whisk well with a fork. Alternatively, you could blend the dressing for smooth consistency. Thin out by adding a tsp of milk, if too thick.
Transfer to a glass jar or container. Dressing tastes best if chilled for 30 minutes. Makes 1 cup and enough for large healthy Caesar salad.
Notes
Store: Refrigerate in a jar for up to 7 days.
More creamy yogurt: Higher fat content yogurt 2% and up will yield creamier dressing. You can use 0% yogurt, if you wish.
Anchovy paste substitute: Try to add more Parmesan, garlic and salt to taste.
